I think a common approach would be using password-derived keys which would _not_ be stored on any server, but could still be used across multiple devices.

> Also, it would be pretty easy to share keys between your devices.

Genuine question: What's the most common and easy way of doing that at the moment?

From your statement about “anyone who gains access to the account would still be able to read and write DMs, even when they would be encrypted” I thought we were looking for an approach that gives more security. Having the account password seed the encryption would still leave us with the same problem.

Easiest way I have seen is when an apple device asks if you want to share the wifi password with another device.
