If you're interested in learning how to implement end-to-end chats with multiple devices, checkout out Wire security whitepaper (https://wire.com/resource/Wire%20Security%20Whitepaper/downl...) for one way of doing it.

Hopefully, OpenWhisperSystems will release documentation about their implementation in Signal (note: it doesn't require phone, unlike WhatsApp)

Thanks! Will definitely read this.

I got fooled by Signal's requirement of a phone for the activation and thought it was also required for normal usage, I guess that's better than Whatsapp, though being able to register and use it without a phone at all would be even better (even Telegram doesn't do this though, IIRC it requires a phone number)

You can just use a one time VoiP phone number if you want to use Signal without your real phone number. That's not optimal, but its pretty neat.

Agreed on phone numbers. Speaking of Wire, it doesn't require them.
