I have multiple users who, starting last week on the same day, are seeing a new sign in screen every time their computers lock or start up. Rather than showing their name and asking for a password, the login screen now shows Other User asking for username, password, and TOTP. Underneath the login field there are sign in options, which allow to sign in normally.
What is more interesting, this issue affected multiple companies across different tenants on the same day, and one of the users has never set up any form of multi-factor authentication on her account.
Group policy has been scoured and anything that looked relevant has been changed, and we have also looked into the registry settings regarding logging in, so far to no avail.
When logging in with safe mode with networking, the sign in option is normal - but of course, this doesn't help for regular usage.
Any help on this issue is greatly appreciated!
