Recently discovered this. Molly supports link with existing device just like on signal desktop. It even has benefit of getting entire chat history unlike signal desktop. Just restore the signal backup file during setup and then click link with existing device. Then scan with you primary phone. Beauty of open source. Molly: https://molly.im/
I’m using molly for several months now it is really nice but recently I dive myself in XMPP and it is superior to molly/signal just because XMPP servers are auditable amd you can actually see if the server is using encryption or not while signal servers are closed source unfortunately, it’s their only flaw
Your client encrypts and decrypts everything, so it is actually not a privacy concern regarding message content when we don’t know what the server does.
The server could decrypt or could be machines attached to the server that store data
Your private key stays at the client, the server doesn’t get it. Verifiable by the source code of your client
Ook thanks
The Signal servers don’t do the encryption, it’s done on your phone. That’s how end-to-end encryption works. Also, Signal’s Server code is FOSS: https://github.com/signalapp/Signal-Server
