**[Signal](https://signal.org/)** | Probably one of the most popular, secure private messaging apps that combines strong encryption (see [Signal Protocol](https://en.wikipedia.org/wiki/Signal_Protocol)) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is [recommended](https://twitter.com/Snowden/status/661313394906161152) by Edward Snowden, and is a perfect solution for most users
**[Session](https://getsession.org)** | Session is a fork of Signal, however unlike Signal it does not require a mobile number (or any other personal data) to register, instead each user is identified by a public key. It is also decentralized, with servers being run by the community though [Loki Net](https://loki.network), messages are encrypted and routed through several of these nodes. All communications are E2E encrypted, and there is no meta data.
**[Silence](https://silence.im/)** | If you're restricted to only sending SMS/MMS, then Silence makes it easy to encrypt messages between 2 devices. This is important since traditional text messaging is inherently insecure. It's easy-to-use, reliable and secure - but has fallen in popularity, now that internet-based messaging is often faster and more flexible
-**[KeyBase](keybase.io/inv/6d7deedbc1)** | KeyBase allows encrypted real-time chat, group chats, and public and private file sharing. It also lets you cryptographically sign messages, and prove your ownership to other social identities (Twitter, Reddit, GitHub, etc), and send or receive Stella or BitCoin to other users. It's slightly more complex to use than Signal, but it's features extend much further than just a messaging app. Keybase core is built upon some great cryptography features, and it is an excellant choice for managing public keys, signing messages and for group chats.

**[Off-The-Record](https://otr.cypherpunks.ca/)** | Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging/ [XMPP](https://xmpp.org). It has fallen in popularity in recent years, in favor for simpler, mobile-based messaging apps, but still widely used and secure. It provides: Encryption (so no one else can read your messages), Authentication (assurance that the correspondent is who you think they are), Deniability (After a conversation, it cannot be proved you took part), Perfect Forwards Secrecy (if your keys are compromised, no previous messages can be decrypted). The easiest way to use OTR, is with a [plugin](https://otr.cypherpunks.ca/software.php) for your IM client
**[OpenPGP](https://www.openpgp.org/)** | Provides cryptographic privacy and authentication, PGP is used to encrypt messages sent over existing chat networks (such as email or message boards). Slightly harder to use (than IM apps), slower, but still widely used. Using [GnuPG](https://gnupg.org/download/index.html), encrypts messages following the OpenPGP standard, defined by the IETF, proposed in [RFC 4880](https://tools.ietf.org/html/rfc4880) (originally derived from the PGP software, created by Phil Zimmermann, now owned by [Symantec](https://www.symantec.com/products/encryption)).
**Note/ Issues with PGP** PGP is [not easy](https://restoreprivacy.com/let-pgp-die/) to use for beginners, and could lead to human error/ mistakes being made, which would be overall much worse than if an alternate, simpler system was used. Do not use [32-bit key IDs](https://evil32.com/) - they are too short to be secure. There have also been vulnerabilities found in the OpenPGP and S/MIME, defined in [EFAIL](https://efail.de/), so although it still considered secure for general purpose use, it may be better to use an encrypted messaging or email app instea - especially for sensitive communications.

ProtonMail has a modern easy-to-use and customizable UI, as well as fast, secure native mobile apps. ProtonMail has all the features that you'd expect from a modern email service and is based on simplicity without sacrificing security. It has a free plan or a premium option for using custom domains (starting at $5/month). ProtonMail requires no personally identifiable information for signup, they have a [.onion](https://protonirockerxow.onion) server, for access via Tor, and they accept anonymous payment: BTC and cash (as well as the normal credit card and PayPal).
**[Tutanota](https://tutanota.com/)** | Free and open source email service based in Germany. It has a basic intuitive UI, secure native mobile apps, anonymous signup, and a .onion site. Tutonota has a full-featured free plan or a premium subscription for businesses allowing for custom domains ($12/ month).
Tutanota [does not use OpenPGP](https://tutanota.com/blog/posts/differences-email-encryption/) like most encrypted mail providers, instead they use a standardized, hybrid method consisting of a symmetrical and an asymmetrical algorithm (with 128 bit AES, and 2048 bit RSA). This causes compatibility issues when communicating with contacts using PGP. But it does allow them to encrypt much more of the header data (body, attachments, subject lines, and sender names etc) which PGP mail providers cannot do

Mailfence has a simple UI, similar to that of Outlook, and it comes with bundled with calendar, address book, and files. All mail settings are highly customizable, yet still clear and easy to use. Sign up is not anonymous, since your name, and prior email address is required. There is a fully-featured free plan, or you can pay for premium, and use a custom domain ($2.50/ month, or $7.50/ month for 5 domains), where BitCoin, LiteCoin or credit card is accepted

See more [privacy-respecting crypto currencies](/5_Privacy_Respecting_Software.md#cryptocurrencies). Note that using crypto anonymously requires some background knowlegde, and the learning curve can be steep, so take care to ensure you're not putting your privacy at risk (see [#70](https://github.com/Lissy93/personal-security-checklist/issues/70))
**Store Crypto Securely** | Advanced | Generate wallet address offline, never let your private key touch the internet and preferably avoid storing it on an internet-connected device. Use a secure wallet, such as [Wasabi](https://www.wasabiwallet.io/), or a hardware wallet, like [Trezor](https://trezor.io/) or [ColdCard](https://coldcardwallet.com/). For long-term storage consider a paper wallet, or a more robust alternative, such as [CryptoSteel](https://cryptosteel.com/how-it-works)
-**Buy Crypto Anonymously** | Advanced | If you are buying a common cryptocurrency (such as BitCoin), purchasing it from an exchange with your debit/ credit card, will link directly back to your real identity. Instead use a service like [LocalBitcoins](https://localbitcoins.com), an anonymous exchange, such as [Bisq](https://bisq.network), or buy from a local BitCoin ATM ([find one here](https://coinatmradar.com)). Avoid any exchange that implements [KYC](https://en.wikipedia.org/wiki/Know_your_customer)
-**Tumble/ Mix Coins** | Advanced | Before converting BitCoin back to currency, consider using a [bitcoin mixer](https://en.bitcoin.it/wiki/Mixing_service), or [CoinJoin](https://en.bitcoin.it/wiki/CoinJoin) to make your transaction harder to trace. (Some wallets, such as [Wasabi](https://www.wasabiwallet.io/) support this nativley)

**Use an Alias Details for Online Shopping** | Advanced | When you pay for goods or services online, you do not know for sure who will have access to your data, or weather it will be stored securley. Consider using an alias name, [forwarding email address](/5_Privacy_Respecting_Software.md#anonymous-mail-forwarding)/ VOIP number, and don't reveal any of your true information. (For Amazon purchases, you can an Amazon gift card with cash, and use an Amazon Locker or local pickup location)
**Use alternate delivery address** | Advanced | When online shopping, if possible get goods delivered to an address that is not associated to you. For example, using a PO Box, forwarding address, corner-shop collection or pickup box
