 **Security** | **Priority** | **Details and Hints**
 --- | --- | ---
-**Use a strong password** | Recommended | Check how strong your password is at [HowSecureIsMyPassword.net](https://howsecureismypassword.net). 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. Have a look at [How Long will it take to Crack my Password](https://www.betterbuys.com/estimating-password-cracking-times/). See [this guide](https://securityinabox.org/en/guide/passwords/) 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 use a password manager.
-**Use different passwords for each account you have** | Recommended | If one password gets compromised, it can give hackers access to your other online sites, so it is highly recommended not to reuse the same passwords. In order to manage having hundreds of different passwords, use a [password manager](https://en.wikipedia.org/wiki/Password_manager). Have a look at [LastPass](https://www.lastpass.com), [DashLane](https://www.dashlane.com), [KeePass](https://keepass.info) or [Robo Forms 8](https://www.roboform.com).
-**Be cautious when logging in on someone else’s device** | Recommended | Ideally you wouldn’t ever log into any of your services on someone else’s device, since you can’t be sure that they don’t have any malware. If you do, ensure that you're in a private session (like Incognito mode) so that nothing gets saved.
-**Avoid password hints** | Optional | It is likely that there is a lot of information about you online, so it can be an easy task for a hacker to find out which high school you went to, or what your mother's name is.
-**Never answer online security questions truthfully** | Optional | Instead, create a password inside your password manager to store your fictitious answer. This will stop people guessing your place of birth or mother's maiden name.
-**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.
+**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 (12+ characters is ideal). Have a look at [HowSecureIsMyPassword.net](https://howsecureismypassword.net) and [How Long will it take to Crack my Password](https://www.betterbuys.com/estimating-password-cracking-times/) to get an idea of what a strong password is.

+**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](https://en.wikipedia.org/wiki/Password_manager).

+**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](http://keepass.info/) is a strong choice.
-**If possible, try to avoid biometric and hardware-based authentication** | Advanced | Fingerprint sensors, face detection and voice recognition are all easily hackable. Where possible replace these with traditional passwords.
-**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](https://www.howtogeek.com/186235/how-to-secure-your-computer-with-a-bios-or-uefi-password/).

 **Consider Switching to Linux** | Optional | Linux is considerably [more secure](https://www.pcworld.com/article/202452/why_linux_is_more_secure_than_windows.html) 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.
