I like the way Voyager does it:

DeltaChat also has a very easy onboarding process: you just put your name, and that's it. The app creates the password in the background and allows you to switch servers easily. That really helps with onboarding new joiners.

Piefed.zip could be a nice default choice. If there are others you see, feel free to suggest.
