XMPP Instant Messaging Quick Start
XMPP (Extensible Messaging and Presence Protocol) is an open standard for instant messaging — think of it as what email is to communication, but for chat. Just like you can email a Gmail user from a Proton Mail account, XMPP lets you message anyone on any XMPP server, regardless of who hosts it.
Quick Start (on Android)
- Install Conversations
- Register a new user in app
