Add logout button to 2FA screen

[Benjamin-K]

Description

Currently, when entering a matching username / password, you are not able to do anything in the backend if you do not have access to the second factor. If a person has access to multiple users, but wanted to login as another user or does not have access to the second factor any more, one has to open the developer tools and remove app data / cookies.

How to solve

Add a second button to the OTP-Screen that allows a user to logout again.
