Ability to choose which apps the login screen unlocks
Very often I'm on a public (or work) computer and only need a few passwords. It seems unesessarily risky to me to have ProtonMail necessarily unlocked in the process! It would be more secure if on the Proton login page, you could choose which Proton apps you want to unlock everytime. In my work I often have to go from my computer to the printers in the other room, and while Proton Pass can lock automatically, ProtonMail doesn't, and it bothers me to potentially give access to my email to anyone passing by.
Please do what's necessary!

I love Proton Pass.
However, with it linked to my Proton Account, logging in to Proton Pass also unlocks Proton Mail and Proton Drive. That's a problem if I want to use Proton Pass on a public (or work) computer, because while Proton Pass can lock itself after a delay, Proton Mail/Drive remains available for anyone accessing the machine. And I can't really choose which one contains the most sensitive data between Mail, Drive and Passwords...
So it would be nice to be able to lock Proton Mail and Proton Drive (and Proton Calendar while we're at it?) after a delay, like Proton Pass, to allow usage of this extension in a not-totally-personal computer.
