Stop Teams remembering accounts

There are apps, like "Deep Freeze" that can be used to reset the entire computer at a specified interval -- say, weekly. It works pretty well for computers that are in a multi-user environment like a lab, but you need to be careful about system/app updates.

Hi,

Unfortunately this is by default whenever the user logs in Teams will remember the userid for the next time to log in by default. Only option is to delete the login manually.

I would suggest to raise a user voice for the same on the below site
