secure messenger
Here is the list of all the messaging services I recommend to use
Matrix defines a set of open APIs for decentralised communication, suitable for securely publishing, persisting and subscribing to data over a global open federation of servers with no single point of control. Uses include Instant Messaging (IM), Voice over IP (VoIP) signalling, Internet of Things (IoT) communication, and bridging together existing communication silos - providing the basis of a new open real-time communication ecosystem.
Element is a Matrix-based end-to-end encrypted (E2EE) secure collaboration and messaging app.
It provides instant messaging, voice and video calls, screen sharing and file sharing; for 1:1s to huge chat rooms. It’s available to use across Web, Android, iOS, macOS, Windows & Linux.
Its decentralised design delivers digital sovereignty, enabling deployment on-premise or through any cloud provider.
Element Matrix Services (EMS) is the most popular SaaS for corporate use of Element. EMS provides fast performance and enterprise-grade add-ons.
Being Matrix-based, Element provides interoperability between traditional siloed apps. It can bridge into proprietary ‘walled garden’ systems such as Slack, Microsoft Teams, WhatsApp, Signal, Telegram and Discord to enable easy connections between different organisations.
End-to-end encryption is provided by default to keep users’ conversations and files safe. Cross-signed device verification uses QR codes or emoji comparisons to guard against imposters and eavesdropping.
Element is built on the Matrix.org open standard which provides bridges to other systems such as Slack, IRC and a lot more soon.
Jami (formerly GNU Ring, SFLphone) positions itself as a potential free Skype replacement

Briar is a messaging app designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate.
- Unlike traditional messaging tools such as email, Twitter or Telegram, Briar doesn't rely on a central server - messages are synchronized directly between the users' devices. If the Internet's down, Briar can sync via Bluetooth or Wi-Fi, keeping the information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.
ChatSecure is a free and open source messaging app that features OTR encryption over XMPP. You can connect to your existing accounts on Facebook or Google, create new accounts on public XMPP servers(including via Tor), or even connect to your own server for extra security.
Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OTR and XMPP, such as Adium, Jitsi, and more.
ChatSecure only uses well-known open source cryptographic libraries to keep your conversations private. Other apps may make claims about 'military grade' security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.

- OTR for verifiable end-to-end encryption and forward secrecy.
- OMEMO for a mobile-friendly alternative to OTR.
