While we are on the topic of Signal, does anyone know if it's possible to have a lock/PIN to open the Signal app itself that's different than your device lock/PIN?

Threema has this feature and it's reassuring to know that people can't open my chats when I hand my phone to someone. Or if I give the device lock/PIN to someone I trust for backup purposes but don't want them to have access to chats themselves.

Last I checked this was not possible with Signal (at least on Android).

For anyone else that's not familiar, this is referring to https://molly.im/ which looks like it's a fork of Signal. And looks like it interops with Signal, so you can talk to your regular Signal contacts as well.

That's very interesting.

My only concern with it would be how sustainable it is in the long term. I am using Threema currently, which has a plan for enterprises, so that seems more reliable but it's lacking in features and usability.

Another concern should be: can you trust molly? Cryptographers have been auditing Signal... who is auditing molly?

In addition, it looks like third-party apps (there are a few) that interface with the official Signal client maybe against Signal's TOS. They haven't enforced it yet from what I can see but it's a possibility and that's a fairy large risk IMO.
