Not federated but you can self host something like this. https://github.com/SillyTavern/SillyTavern

Continue what you’re doing on the desktop and set up beeper with only your Facebook account to handle messages from your phone. It’s still not great, but I think it’s the best you’re going to get. You’re really only gaining Facebook, not seeing where you’re connecting from. Also, Beeper is just a pretty front end to a matrix server with a bridge connecting to Facebook Messenger. You could totally run it yourself if you wanted; check out the “self-host” link near the bottom of the page.

• allows any two computers to transfer data (using a relay)
• provides end-to-end encryption (using PAKE)
• enables easy cross-platform transfers (Windows, Linux, Mac)
• allows multiple file transfers
• allows resuming transfers that are interrupted
• local server or port-forwarding not needed
• ipv6-first with ipv4 fallback
• can use proxy, like tor

It’s the default on all my devices, works just fine.
