Passwords

Most reported data breaches are caused by the use of weak, default or stolen passwords (according to this Verizon report). Massive amounts of private data have been, and will continue to be stolen because of this.

Use strong passwords, which can't be easily guessed or cracked. Length is more important than complexity (at least 12+ characters), although it's a good idea to get a variety of symbols. Ideally you should use a different and secure password to access each service you use. To securely manage all of these, a password manager is usually the best option. This guide gives a lot more detail about choosing and managing passwords.

Security	Priority	Details and Hints
Use a strong password	Recommended	Try to get a good mixture of upper and lower-case letters, numbers and symbols. Avoid names, places and dictionary words where possible, and aim to get a decent length (a minimum of 12+ characters is ideal). Have a look at HowSecureIsMyPassword.net and How Long will it take to Crack my Password to get an idea of what a strong password is. See this guide for more information.
Don’t save your password in browsers	Recommended	Most modern browsers offer to save your credentials when you log into a site. Don’t allow this! As they are not always encrypted, hence can allow someone to gain easy access into your accounts. Also do not store passwords in a .txt file or any other unencrypted means. Ideally reputable use a password manager.
Use different passwords for each account you have	Recommended	If your credentials for one site gets compromised, it can give hackers access to your other online accounts. So it is highly recommended not to reuse the same passwords. Again, the simplest way to manage having many different passwords, is to use a password manager. Have a look at LastPass, DashLane, KeePass or Robo Forms 8.
Be cautious when logging in on someone else’s device	Recommended	When using someone else's machine, ensure that you're in a private session (like Incognito mode, Crt+Shift+N) so that nothing gets saved. Ideally you should avoid logging into your accounts on other peoples computer, since you can't be sure their system is clean. Be especially cautious of public machines, or when accessing any of your secure accounts (email, banking etc).
Avoid password hints	Optional	Some sites allow you to set password hints. Using this feature makes it easier for hackers.
Never answer online security questions truthfully	Optional	If a site asks security questions (such as place of birth, mother's maiden name or first car etc), don't provide real answers. It is a trivial task for hackers to find out this information. Instead, create a password inside your password manager to store your fictitious answer.
Don’t use a 4-digit PIN to access your phone	Optional	Don’t use a short PIN to access your smartphone or computer. Instead, use a text password. Pins or numeric passphrases are much easier crack, (A 4-digit pin has 10,000 combinations, compared to 7.4 million for a 4-character alpha-numeric code).
Use an offline password manager	Advanced	Consider an offline password manager, encrypted by a strong password. If you work across two or more computers, this could be stored on an encrypted USB. KeePass is a strong choice.
If possible, try to avoid biometric and hardware-based authentication	Advanced	Fingerprint sensors, face detection and voice recognition are all hackable. Where possible replace these with traditional strong passwords.

2-Factor Authentication

This is a more secure method of logging in, where you supply not just your password, but also an additional code usually from a device that only you have access to.

2FA Apps: Authy (with encrypted sync), Google Authenticator, Microsoft Authenticator, FreeOTP (open souce), LastPassAuthenticator (synced with your LastPass), Duo and Authenticator Plus.

Security	Priority	Details and Hints
Enable 2FA on Security Critical Sites	Recommended	In account settings, enable 2-factor authentication. Ideally do this for all your accounts, but at a minimim for all security-scritical logins, (including your password manager, emails, finance and social sites). List of sites that support 2FA.
Keep backup codes safe	Recommended	When you enable 2FA, you'll be given a few one-time codes to download, in case you ever lose access to your authenticator app or key. It's important to keep these safe, either encrypt them and store on a USB, or print them on paper and store them somewhere secure like a locked safe. Delete them from your computer once you've made a backup, incase your PC is compromised.
Don't use SMS to recieve OTPs	Optional	Although SMS 2FA is certenly better than nothing, but there are many weaknesses in this system, ( such as SIM-swapping) (read more), therefore avoid enabling SMS OTPs, even as backups.
Don't use your Password Manager to store 2FA tokens	Optional	One of the quickest approachs is to use the same system that stores your passwords, to also generate and fill OTP tokens, both LastPass and 1Password have this functionality. However if a malicious actor is able to gain access to this, they will have both your passwords, and your 2FA tokens, for all your online accounts. Instead use a seperate authenticator from your password manager.
Consider a hardware 2FA Key	Optional	A physical 2FA key generates an OTP when inserted. Have a look at NitroKey (open source), YubiKey or Solo Key. You can also use it as a secondary method (in case your phone is lost or damaged). If this is your backup 2FA method, it should be kept somewhere secure, such as a locked safe, or if you use as physical key as your primary 2FA method, then keep it on you at all times.

Browser and Search

Most modern web browsers support add-ons and extensions, these can access anything that you do online, avoid installing anything that may not be legitimate and check permissions first. Be aware that ever website that you interact with, including search engines will likely be keeping records of all your activity. Last year Kaspersky reported over a million data exploits caused by malicious sites.

For more browser security pointers, check out: Here’s How To Get Solid Browser Security.

Security	Priority	Details and Hints
Deactivate ActiveX	Recommended	ActiveX is barley used nowadays, but Microsoft browsers have it enabled by default. It acts as a middleware between Java and Flash applications and your PC. But it is commonly used for malicious sites to run scripts directly on your PC. See this article for more details.
Disable Flash	Recommended	Adobe Flash has been around since the dawn of the internet, however it has been falling in popularity for a while. It brings with it many unpatched vulnerabilities (a few of which you can read about here). See this guide, on how to disable Flash player, or this guide for more details on how dangerous it can be.
Block Trackers	Recommended	Consider installing a browser extension, such as Privacy Badger, to stop advertisers from tracking you in the background.
Block scripts from bad origin	Recommended	Use an extension such as uBlock Origin, to block anything being loaded from an external or unverified origin.
Force HTTPS only traffic	Recommended	Using an extension such as HTTPS Everywhere, wil force all sites to load securely.
Only use trusted browser add-ons and extensions	Recommended	Both Firefox and Chrome web stores allow you to check what permissions/access rights an extension requires before you install it. Check the reviews. Only install extensions you really need, and removed those which you haven't used in a while. Extensions are able to see, log or modify anything you do in the browser, and some innocent looking browser apps, have malitious intentions.
Always keep your browser up-to-date	Recommended	Browser vulnerabilities are constantly being discovered and patched, so it’s important to keep it up to date, to avoid a zero-day exploit. You can see which browser version your using here, or follow this guide for instructions on how to update.
Use a private search engine	Optional	Google tracks, logs and stores everything you do, but also displays biased results. Take a look at DuckDuckGo or StartPage. Neither store cookies or cache anything. Read more about Google Search Privacy.
Consider a privacy browser	Optional	Google openly collects usage data on Chrome usage. There are several privacy browsers out there which minimise the amount of data collected. The most popular of which is Brave Browser, or Firefox. Others include Bromite, Epic Browser or Comodo. The most secure option is Tor Browser.
Use DNS-over-HTTPS	Optional	Traditional DNS makes requests in plain text for everyone to see, it allows for eavesdropping and manipulation of DNS data by man-in-the-middle attacks. Whereas DNS-over-HTTPS performs DNS resolution via the HTTPS protocol, meaning data between the you and your DNS resolver is encrypted. You can follow this guide to enable in Firefox, for see CoudFlares 1.1.1.1 Docs.
Disable WebRTC	Optional	WebRTC allows high-quality audio/ video communication and peer-to-peer file-sharing straight from the browser. However it can pose as a privacy leak, especially if you are using a proxy or VPN. In FireFox WebRTC can be disabled, by searching for, and disabling media.peerconnection.enabled in the settings. For other browsers, the WebRTC-Leak-Prevent extension can be installed. uBlockOrigin also allows WebRTC to be disabled. To learn more, check out this guide.
Don't Connect to Open WiFi networks	Optional	Browing the internet while using public or open WiFi may leave you vulnrable to man-in-the-middle attacks, malware distribution or snooping and sniffing. Some hotspots may also be unencrypted, or even malicious. If you do need to briefly use a public WiFi network, ensure you disable file sharing, only visit HTTPS websites and use a VPN. Also remove the network from your saved WiFi list after. See the networking section for more details.
Use Tor	Advanced	The Tor Project privides a browser that encrypts and routes your traffic through multiple nodes, keeping users safe from intercaption and tracking. The draw backs are speed and user experience, but it is the most secure browser option.
Disable JavaScript	Advanced	Many modern web apps are JavaScript based, so disabling it will greatly decrease your browsing experience. But if you really want to go all out, then it will reduce your attack surface. Read more about the growing risk of JavaScript malware.
Route all desktop traffic via Tor	Advanced	Whonix allows for fail-safe, automatic, and desktop-wide use of the Tor network. It's based on Debian, and runs in in a virtual machine. Straigt-forward to install on Windows, OSX or Linux.

Emails

Nearly 50 years since the first email was sent, they’re still very much a big part of our day-to-day life, and will probably continue to be for the near future. So considering how much trust we put in them, it’s surprising how fundamentally insecure this infrastructure is. Email-related fraud is on the up, and without taking basic measures you could be at risk.

If a hacker gets access to your emails, it provides a gateway for your other accounts to be compromised, therefore email security is paramount for your digital safety.

It's strongly advised not to use non-encrypted email, but if you follow these guides for simple steps to improve security: Yahoo, Gmail, Outlook and AOL. The easiset way to stay protected, it to use a secure mail provider, such as ProtonMail.

Security	Priority	Details and Hints
Have more than one email address	Recommended	Keeping your important and safety-critical messages separate from trivial subscriptions such as newsletters, is a very good idea. Be sure to use different passwords. This will also make recovering a compromised account after an email breach easier.
Keep security in mind when logging into emails	Recommended	Your email account is one of the most important to protect with a secure password. Only sync your emails with your phone, if it is secured (encrypted with password). Don’t allow your browser to save your email password. Prevent man-in-the-middle attacks by only logging in on a secured browser.
Always be wary of phishing and scams	Recommended	If you get an email from someone you don’t recognize, don’t reply, don’t click on any links, and absolutely don’t download an attachment. Keep an eye out for senders pretending to be someone else, such as your bank, email provider or utility company. Check the domain, read it, ensure it’s addressed directly to you, and still don’t give them any personal details. Check out this guide, on how to spot phishing emails.
Don’t share sensitive information over email	Optional	Emails are very very easily intercepted. Also you can’t know how secure your recipients environment is. Don’t share anything personal, such as bank details, passwords, confidential information over email. Ideally, don’t use email as a primary method of communication.
Don’t connect third-party apps to your email account	Optional	If you give a third-party app (like Unroll.me) full access to your inbox, this makes you vulnerable to cyber attacks. The app can be compromised and, as a consequence, cyber criminals would gain unhindered access to all your emails and their contents.
Consider switching to a more secure email provider	Optional	Email providers such as ProtonMail, CounterMail, HushMail (for business users) or MailFence allow for end-to-end encryption, full privacy as well as more security-focused features. See this guide for a details of the inner workings of these services.

Social Media

Security	Priority	Details and Hints
Check your privacy settings	Recommended	Most social networks allow you to control your privacy settings. Ensure that your profile can only be viewed by people who you are in your friends list, and you know personally.
Only put info on social media that you wouldn’t mind being public	Recommended	Even with tightened security settings, don’t put anything online that you wouldn’t want to be seen by anyone other than your friends. Don’t rely solely on social networks security.
Don’t give social networking apps permissions they don’t need	Recommended	By default many of the popular social networking apps, will ask for permission to access your contacts, your call log, your location, your messaging history etc.. If they don’t need this access, don’t grant it.
Revoke access for apps your no longer using	Recommended	Instructions: Facebook, Twitter, LinkedIn, Instagram.
Use a secure email provider	Optional	Most email providers completely invade your privacy intercepting both messages sent and received. ProtonMail is a secure email provider, that is open source and offers end-to-end encryption. There are alternative secure mail providers (such as CounterMail, HushMail and MailFence)- but ProtonMail has both a clear interface and strong security record.
Remove metadata before uploading media	Optional	Most smartphones and some cameras automatically attach a comprehensive set of additional data to each photograph., This usually includes things like time, date, location, camera model, user etc. Remove this data before uploading. See this guide for more info.
Don’t have any social media accounts	Advanced	It may seem a bit extreme, but if your serious about data privacy and security, stay away from entering information on any social media platform.

Networking

This section covers how you connect your devices to the internet, including configuring your router and setting up a VPN.

A Virtual Private Network (VPN) protects your IP, and allows you to more securely connect to the internet. Use it when connecting to public WiFi or to restrict your ISP from seeing all sites you've visited. Note, VPNs are not a perfect solution, and it is important to select a reputable provider, to entrust your data with. Tor provides greater anonimity.

Security	Priority	Details and Hints
Use a VPN	Recommended	Use a reputable, paid-for VPN. Choose one which does not keep and logs and preferably is not based under a 5-eyes jurisdiction. See That One Privacy Site for a detailed comparison. As of 2020, NordVPN and SurfShark are both good all-rounders (for speed, simplicity and security), and Mullvad, OVPN and DoubleHop are excelland for security.
Don’t use a default router password	Recommended	Change your router password- here is a guide as to how.
Use WPA2	Recommended	WPA and WEP make it very easy for a hacker to gain access to your router. Use a WPA2 password instead. Ensure it is strong: 12+ alpha-numeric characters, avoiding dictionary words.
Keep router firmware up-to-date	Recommended	Manufacturers release firmware updates that fix security vulnerabilities, implement new standards and sometimes add features/ improve the performance your router. It's important to have the latest firmware installed, to avoid a malicious actor exploiting an un-patched vulnerability. You can usually update your router by navigating to 192.168.0.1 or 192.168.1.1 in your browser, entering the credentials on the sticker on the back of you of your router (not your WiFi password!), and following the on-screen instructions. Or follow a guide from your routers manufacturer: Asus, D-Link, Linksys (older models), NetGear and TP-Link. Newer Linksys and Netgear routers update automatically, as does Google's router.
Configure your router to use VPN	Optional	If you set your VPN up on your router, then data from all devices on your home network is encrypted as it leaves the LAN. Again, it's important to select a secure VPN provider, as they will see what your ISP previously had been logging. Follow a guide from your router manufacturer or VPN provider, or see this article to get started. Note that depending on your internet connection, and VPN provider, this could slow down your internet.
Stay protected from DNS Leaks	Optional	A DNS leak is the act of monitoring, storing and filtering your DNS traffic at ISP level. To prevent this you can either use a DNS server provided by your VPN, or use CloudFlares DNS (set nameservers to 1.1.1.1), or maintain your own DNS server. You can check your protection, by running a DNS Leak Test, or run nslookup whoami.akamai.net in your terminal. Read more about preventing DNA Leaks.
Use a secure VPN Protocol	Optional	OpenVPN is widley used, and currently considered a secure tunneling protocol, it's also open source, lightweight and effiecient. L2TP can be good, but only when configured correctly, whereas it's much harder to go wrong with OpenVPN. Don't use PPTP, which is now legacy, and not considered secure, and avoid SSTP (proprietary, owned by Microsoft and due to lack of transparency, could be vulnrable to exploits). IKEv2 and WireGuard (experimental) are also good options.
Avoid the free router from your ISP	Optional	Typically they’re manufactured cheaply in bulk in China, and firmware updates which fix crucial security flaws aren’t released regularly. Consider an open source based router, such as Turris MOX
Ideally hide your SSID	Optional	An SSID (or Service Set Identifier) is simply your network name. If it is not visible, it is much less likely to be targeted. You can usually hide it after logging into your router admin panel, see here for more details.
Whitelist MAC Addresses	Optional	As well as a strong password, and hidden SSID, you can whitelist MAC addresses in your router settings, disallowing any unknown devices to immediatley connect to your network, even if they know your credentials. A malicous actor can bipass this, by cloning their address to appear the same as one of your trusted devices, but it will add an extra step for them.
Secure DNS	Advanced	Use DNS-over-HTTPS which performs DNS resolution via the HTTPS protocol, encrypting data between the you and your DNS resolver. See CoudFlares 1.1.1.1 Docs for more details. Don't use Google DNS or other services which collect a lot of data.
Use the Tor Network	Advanced	VPNs have their weaknesses, since the provider knows your real details, whereas Tor is anonymous. For optimum security, route all your internet traffic through tthe Tor network. On Linux you can use TorSocks and Privoxy, for Windows you can use Whonix, and on OSX follow thsese instructions. Finally, you can use OnionPi to use Tor for all your connected devices, by configuring a Raspberry Pi to be a Tor Hotspot
Change your Routers Default IP	Advanced	Modifying your router admin panels default IP address will makes it more difficult for malicious scripts in your web browser targeting local IP addresses, as well as adding an extra step for local network hackers
Kill unused process and services on your router	Advanced	Services like Telnet and SSH (Secure Shell) that provide command-line access to devices should never be exposed to the internet and should also be disabled on the local network unless they're actually needed. In general, any service that’s not used should be disabled to reduce attack surface.
Disable WiFi on all Devices	Advanced	Connecting to even a secure WiFi network increases your attack surface. Disabling your home WiFi and connect each device via Ethernet, and turning off WiFi on your phone and using a USB-C/ Lightening to Ethernet cable will protect against WiFi exploits, as Edward Snowden says here.

Mobile Devices

Most smart phone apps will run in the background, collecting and logging data, making network requests and ultimately creating a clear picture of you you are, just from your data. This is a big problem from both a security and privacy perspective.

Even non-smart phones, (and even when the screen is off) are constantly connecting to the nearest cell phone towers, (it does this by broadcasting it's IMEI and MEID number). The towers then relay this information, along with any communications, to your mobile carrier, who will store these records indefinitely. The movements of your phone are the movements of you as a person, so all phone proximity and data records can always be linked directly back to you. So whenever your phone is on, there is a record of your presence at that place, being created and maintained by companies.

SMS texting and traditional phone calls are not secure, so it's imprortant to avoid using that to send or recieve anything secure (such as log in codes, OTPs or any personal details). Instead use encrypted messaging, like Signal whenever you can. Be wary of who you share your phone number with.

Security	Priority	Details and Hints
Turn of connectivity features that aren’t being used	Recommended	When you're not using WiFi, Bluetooth, NFC or anything else, turn those features off. These are commonly used to easily hack individuals.
Keep app count to a minimum	Recommended	Uninstall apps that you don’t need or use regularly. As apps often run in the background, slowing your device down, but also collecting data.
Don’t grant apps permissions that they don’t need	Recommended	If an app doesn’t need access to your camera, don’t grant it access. Same with any features of your phone, be wary about what each app has access to.
Only install Apps from official source	Recommended	Applications on Apple App Store and Google Play Store are scanned and cryptographically signed, making them less likley to be malicious. Avoid downloading .apk or .ipa files from unverified source. Also check the reviews before downloading a new application.
Only Charge your Device from a Trusted Source	Recommended	When you charge your device via USB in a public space, it is possible for malicious actors to gain full access to your device, via AT Commands. You can read more about this at https://atcommands.org/ or from this seminar. To protect yourself, either only charge your phone from trusted sources, or use a USB Data Blocker. A Data blocker allows your phone to charge, while blocking the data transfer wires, blocking this exploit or any file transfers to run. (PortaPow is recomended, since it still allows for fast-charge.) Availible in both USB-A and USB-C.
Set up a mobile carrier pin	Recomended	SIM hijacking is when a hacker is able to get your mobile number transfered to their sim (often through social engineering your mobile carrier). This then allows them to recieve 2FA SMS codes (enabling them to access your secure accounts, such as banking), or to pose as you. The easiest way to protect against this is to set up a PIN through your mobile provider, thus disallowing anyone without this PIN to make any changes to your account. The PIN should not be easily guessible, and it it important that you remember it, or store is somewhere secure. Using a non-SMS based 2FA method will reduce the damage that can be done if someone is able to take control of your SIM. Read more about the sim swap scam.
Opt-out of personal adds	Optional	In order for adds to be personalized, Google collects data about you, you can slightly reduce the amount they collect by opting-out of seeing personalised ads. See this guide, for Android instructions.
Erase after too many login attempts	Optional	To protect against an attacker brute forcing your pin, if you loose your phone, set your device to erase after too many failed login attempts. See this iPhone guide. You can also do this via Find my Phone, but this increased security comes at a cost of decreased privacy.
Monitor Trackers	Optional	A tracker is a piece of software meant to collect data about you or your usages. εxodus, is a great service, which lets you search for any app, by it's name, and see which trackers are embeded in it. They also have an app, which shows trackers and permissions for all your installed apps.
Install a Firewall	Optional	To prevent applications from leaking privacy-sensitive data, you can install a firewall app. This will make it easier to see and control which apps are making network requests in the background, and allow you to block specific apps from roaming when the screen is turned off. For Android, check out NetGuard, and for iOS there is LockDown, both of which are open source. Alternatively there is NoRootFirewall Android, XPrivacy Android (root required), Fyde iOS and Guardian Firewall iOS.
Use secure, privacy-respecting apps	Optional	Mainstream apps have a reputation for not respecting the privacy of their users, and they're usually closed-source meaning vulnrabilities can be hidden. Prism-Break maintains a list of better alternatives, see Android and iOS.
Use Signal, insted of SMS	Optional	SMS may be convinent, but it's no secure. Signal is both the most secure and private option. Silence (encrypted SMS), Threema, Wire(enterprise) and Riot are also encrypted.iMessage and WhatsApp do claim to be end-to-end-encrypted, but since they are not open source, verifying this is harder, and the private companies which own them (Apple and Facebook), have a questionable reputation when it comes to protecting users privacy. Keep in mind that although the transmission may be secured, messages can still be read if your, or your recipients' devices have been compromised.
Avoid using your real phone number when signing up for an account or service	Optional	Where possible, avoid giving out your real phone number while creating accounts online. You can create phone numbers using services such as Google Voice or Skype. For temporary usage you can use a service like iNumbr that generates a phone number that forwards messages and calls to your main number.
Watch out for Stalkerware	Optional	This is malware that is installed directly onto your device by someone you know (partner, parent, boss etc). It allows them to see your location, messages and other app data remotley. The app likley won't show up in your app draw, (but may visible in Settings --> Applications --> View All). Sometimes they can be disguised as a non-conspicuous app (such as a game, flashlight or calculator) which initially don't appear suspicious at all. Look out for unusual battery ussage, network requests or high device temperature. If you suspect that stalkerware is on your device, the best way to get rid of it, is though a factory reset. See this guide for more details.
Sandbox Mobile Apps	Advanced	Prevent permission-hungry apps from accessing your private data with Island. It is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including call logs, contacts, photos and etc) even if related permissions are granted.
Consider Orbot	Advanced	Orbot provides a system-wide Tor connection. Although more secure than a VPN, it may be slower- see Networking section for more details.
Consider running a custom ROM if you have an Android device	Advanced	Your default OS tracks information about your usage, and app data, constantly. Consider a security-focused custom ROM, such as Lineage or CopperheadOS.

Personal Computers

Although Windows and OS X are easy to use and convenient, they both are far from secure. Your OS provides the interface between hardware and your applications, so if compromised can have detrimental effects.

Security	Priority	Details and Hints
Keep your OS up-to-date	Recommended	Microsoft, Apple and Google release regular OS updates, which fix security risks. Always keep your device updated.
Encrypt and Backup Important Files	Optional	Backing up your phone can help keep your important data safe, if your device is lost, stolen or broken. But without encrypting it, cloud services will have access to it (if you don't pay for the service, then you are the product!). Cryptomator is an open source tool that makes this easy. It also works alongside MountainDuck for mounting your remote drives on Windows and Mac. Other non-open-source options are BoxCrypter, Encrypto and odrive.
Consider Switching to Linux	Optional	Linux is considerably more secure than both OSX and Windows. Some distros are still more secure than others, so it’s worth choosing the right one to get a balance between security and convenience.
Avoid PC Apps that are not secure	Optional	Mainstream apps have a reputation for not respecting the privacy of their users, and they're usually closed-source meaning vulnrabilities can be hidden. See here for compiled list of secure PC apps for Windows, OSX and Linux.
Use a Security-Focused Distro	Advanced	QubeOS is based on “security by compartmentalization”, where each app is sandboxed. Whonix is based on Tor, so 100% of your traffic will go through the onion router. Tails is a has no persistent memory, and is ideal if you don’t want to leave a trace on the device your booting from. Subgraph is an “adversary resistant computing platform”, but also surprisingly easy to use
Password protect your BIOS and drives	Advanced	A BIOS or UEFI password helps to make an inexperienced hackers life a bit harder if they get a hold of your PC or hard drive, here is a guide on how to do it.
Canary Tokens	Advanced	Network breaches happen, but the longer it takes for you to find out about it, the more damage is done. A canary token is like a hacker honeypot, something that looks appealing to them once they've gained access to your system. When they open the file, unknowingly to them, a script is run which will not only alert you of the breach, but also grab some of the hackers system details. CanaryTokens.org and BlueCloudDrive are excellent sites, that you can use to generate your tokens. Then just leave them somewhere prominent on your system. Learn more about canary tokens, or see this guide for details on how to create them yourself.

Smart Home

Home assistants (such as Google Home, Alexa and Siri) and other internet connected devices collect large amounts of personal data (including voice samples, location data, home details and logs of all interactions). Since you have limited control on what it being collected, how it's stored, and what it will be used for, this makes it hard to recommend any consumer smart-home products to anyone who cares about privacy and security.

Security vs Privacy: There are many smart devices on the market, that claim to increase the security of your home, while being easy and convenient to use (Such as Cave Burglar Alarm, Blink Cam, Yale Lock and Ring Doorbell to name a few). These devices may appear to make security easier, but there is a trade-off in terms of privacy: as they collect large amounts of personal data, and leave you without control over how this is stored or used. The security of these devices is also questionable, since many of them can be (and are being) hacked, allowing an intruder to bypass detection with minimum effort.

The most privacy-respecting option, would be to not use "smart" internet-connected devices in your home, and not to rely on a security device that requires an internet connection. But if you do, it is important to fully understand the risks of any given product, before buying it. Then adjust settings to increase privacy and security. The following checklist will help mitigate the risks associated with internet-connected home devices.

Security	Priority	Details and Hints
Rename devices to no specify brand/model	Recommended	If your device name shows what brand or model it is, it will make it easier for a malicious actor launch an attack targeting a specific device. For example avoid names like "Nest Cam", "Yale Lock YRD 256" or "Hive Thermostat". It's uaually easy to change the devices default name.
Disable microphone and camera when not in use	Recomended	Smart speakers and other voice controlled devices store sound clips on a server (and sometimes monitored by employees to improve the speach detection), any accidental recordings could disclose sensetive or personal data. A targetted attach could also allow someone to gain controll of a microphone/ camera, so using the hardware switch to turn it off will help protect from that.
Understand what data is collected, stored and transmitted	Recommended	Before purchasing any smart home device, do some research - and ensure that you understand, and are comfortable with what is being collected and how it is stored and used. Don't buy devices that share anything with third parties, and check the data breech database.
Set privacy settings, and opt out of sharing data with third parties	Recommended	Once installed, go to settings in the app, and under privacy ensure the strictest options are selected. Usually by default, the most possible data is being collected.
Don't link your smart home devices to your real identity	Recommended	Use a unique user name and password which does not identify you, your family, your location or any other personal details. When creating an account for a new smart home device, do not sign up/ log in with Facebook, Google or any other third-party service.
Keep firmware up-to-date	Recommended	Ensure firmware versions on smart devices is up-to-date and software patches have been applied. Most smart home apps will notify you when a new firmware version is available, so all you have to do it accept and install.
Protect your Network	Recommended	On many smart home devices, anybody connected to your home WiFi is able to view device content (such as camera footage, or motion statistics). So ensure that your WiFi and home networks are properly secured with a strong password and up-to-date firmware. (See the Router Section for more details)
Be weary of wearables	Optional	Wearable smart devices allow companies to log even more data than ever before, they can track your every move to know exactly where you are and what you are doing at any given time. Again, you as the consumer have no control over what is done with that data.
Don't connect your homes critical infrastructure to the internet	Optional	While a smart thermostat, burglar alarm, smoke detector and other appliances may seem convenient, they by design can be accessed remotely, meaning a hacker can gain control of your entire home, without even needing to be near by.
