I agree for both mobile and web applications. It is discouraging that if somebody gains access to my computer if I step away for my phone they could easily access my Lumo threads. The path that Proton used for ProtonPass would be a great option for this. Add the option for a second password, with the additional option to implement a 6 digit pin number for ease of access.

Yeah, I agree, that's a critical issue that needs to be fixed

This is such a basic criterion. It needs fixing. Yes, we could use the web interface, but I think I'm right in saying that when logged in, the chats become available cross-platform?

Ya this is a critical issue I would just use the web version for now.

If you log in with your proton acount in Lumo, you have immediat access to all your account and keys via browser when selecting Settings under the account tab. If you cannot lock the app woth Biometrics or at least a pin, that a clear security issue.

I immediately signed out when I saw this..

Please fix it.
