I am a firm believer that there are many privacy techniques you should focus on before encrypted messaging because they will offer you much more “bang for your buck,” things like good passwords, two-factor authentication, and even encrypted email. That said, I still believe that encrypted messaging is a critical part of a well-rounded privacy and security strategy. While the vast majority of our day-to-day conversations may be benign, it can still offer a lot of insight into who we are as people – our routines, likes, and personal thoughts. This information – mundane or not – is worth protecting.
TLDR: Avoid Telegram and WhatsApp. Recommended messengers are Session, Signal, SimpleX and Threema. Honorable mention: Briar.
Session should probably be avoided as well, primarily because they’ve disabled things like perfect forward secrecy and a few other security measures that probably should not have been disabled.
OK, WhatsApp is owned by Meta and it is proprietary, but why not Telegram?
Effectively does not have end-to-end, phone number required and overall hard to use anonymously, etc.
