Description
Hopefully not a dupe. One of the features I particularly enjoy about Signal is the possibility of setting a screen lock with a timeout that will restrict access to the application even if the phone is unlocked. As keybase is often used to communicate sensitive information much like Signal is, I think this would be a welcome addition.
On iOS, the relevant API is LocalAuthentication from what I can tell.
I haven't really looked for android, but the APIs are probably FingerprintManagerCompat or the newer BiometricPrompt.
If it's easy I might find a few hours and put together a PR. Upvote if you want this feature.

Research direction
The issue names no files, tests, or entry points. Start by reviewing the iOS LocalAuthentication API and the Android FingerprintManagerCompat or BiometricPrompt APIs, then locate the mobile screen-lock flow. Done means the app can enforce a configurable timeout and restrict access with biometric authentication on both platforms.
