Simplifying unlock of app when using E2EE

[p-sims]

Feature Description

Currently you have to unlock your device using passcode or TouchID/FaceID before you put in your E2E password. (if you choosing not to get iOS to save it). Should there be an option to not require phone unlock if asking for E2E password to avoid having two stage unlocking process?

If this was possible then there would need to be a timeout that locked password app again if you switched apps for more than say 1 minute or 30 seconds.

Rationale

To avoid having two stage passcode entry process to unlock app. If you choose to require E2E password to be entered everytime, then you should be able to turn off the requirement for iOS authentification everytime you switch to the app.
