Signal desktop doesn't even have a PIN to unlock it. IIRC the reason was that if someone is already on your machine then you're screwed.
I just want it to stop someone like my son, who may have access to my computer legitimately, from seeing some of the NSFW messages me and my friends send each other.
Just make a separate user acct for the kid. That way your stuff is separate and you can also implement parental controls if needed.
Yeah, we have separate profiles, but sometimes I just let him use some software on mine, like a game, or whatever, and then I go and do something else. The use-case is there, along with encrypted messages, but people say things like what you said because they don't personally have that use-case.
I'd look at implementing it myself, but they wouldn't merge it, and I'm not going to maintain a fork indefinitely.
For your use case, running a VM on your desktop should be sufficient. The VM could have disc encryption. So when you're letting somebody else use your terminal, they can't access your interesting messages.
Hyper-V has this built in I believe, QEMU does it as well, UTM on Mac OS makes it pretty easy. But there's a thousand different ways to skin this cat
Most sensible way in my opinion would be for the Signal app to have a PIN and encryption on desktop, just like it already does on the mobile apps.
