@bob "hey we need something to base our super secure IM app; I know, let's use this thing that tracks Chromium but is always a version or two behind, so vulnerabilities fixed in Chromium are already public even though we had no time to release a version that contains the fixes".

The email protocol is not very famous for security, but "everyone" uses it.
F-Droid has two clients which organises email-conversations as chats!
So almost universal chat app!
They do provide security built in, I presume

You might miss video/audio chat.
I haven't tried them.
@rysiek I set it up on matrix.opencloud.lu and tested it with a few people before opening it up. You have to pair the devices by confirming codes and it warns you if any unconfirmed device has joined the conversation. Haven't done any audit or security testing on it. By next week I should be able to open it and if you wish we can run some tests. @bob @neb
