Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
To remove a work account from Microsoft Authenticator, remove that account from the app:
- Open Microsoft Authenticator.
- Select the work account to remove.
- Tap the Settings gear.
- Tap Remove account.
Important:
- After removing the account, that device can no longer be used to verify sign-in for that account.
- If the account was your last or only account in Authenticator, removing all accounts effectively signs out of the app.
If the Remove account option is not available for that specific account:
- On the phone, open Settings.
- Go to the device account area. The name can vary, such as Accounts, Accounts & sync, or Accounts and backup.
- If the old work or school account is listed there, remove it.
- Restart the device and check Authenticator again.
- If the account is tied to an Android Work Profile, remove the Work Profile.
- Sign out of other Microsoft apps on the device, such as Outlook, Teams, OneDrive, or Microsoft 365, because they can keep the account present.
If the account still cannot be removed individually, the documented fallback is to remove all accounts from Authenticator by clearing the app data.
On Android:
- Open Settings > Apps.
- Select Authenticator.
- Select Storage or Storage & cache.
- Tap Clear data > OK.
Warning: there is no undo. All accounts will be removed, and the device will no longer be usable to verify sign-in for any of those accounts.
If Authenticator backup exists and needs to be removed as well:
- Open Authenticator > Settings.
- Under Backup, turn off Cloud Backup.
- Select OK to delete the backup.
