Ok so, here I am again asking another question 🙈🙊 But hear me out: I read this post here about, if there even is a good privacy messenger that can be trusted. Someone in the comments mentioned Conversations (a XMPP client for Android). This made me look into XMPP and at the moment I am giving Conversations a try. Reading into XMPP, I couldn’t find a problem security or privacy wise. Also it seems like it does not matter what server I use (atm. we are on 07f.de) since it is all e2e with OMEMO. Am I missing something or is it really this good? And if I dont trust anyone, I could host my one instance of ejabberd, right?
There are some clients that support the latest version of OMEMO, but yes, since the most popular ones do not, you end up using the older version most of the time. That said, the older version is not generally unsafe, it basically is the same as WhatsApp or Signal are using. The newer version is just somewhat better as it includes some lessons learned from earlier attempts.
