Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello, I’m Virginia, a fellow user like yourself.
Sorry to hear you’re experiencing problems.
When asked for a code there should be another option to enter your password instead.
Deleting the Authenticator account wouldn’t work as it doesn’t turn off 2 factor authentication. Was the app set to backup to the cloud? If so & the backup is dated before you removed the account/s then you can delete & reinstall the app & during set up choose recovery. Otherwise you’d have to use one of the backup codes shown during setting up 2 factor authentication.
We have no access to accounts so cannot turn off this feature for you & Microsoft cannot do this either.
If you’re using Windows/Authenticator in a work environment then you may also post on a more dedicated forum for corporate users:
