The feature

Hi all!
Just discovered this incredible Immich app, thanks for all the job done, this is really impressive.

I'm proposing here to add a feature on the mobile apps: I would like to have the app locked, and ask to unlock via PIN and / or biometrics each time I want to open it.
This will add a nice safety / privacy layer on top of the things.

Thanks!
