Hi,
Thank you for posting in Microsoft Community.
Based on your description, It seems like you’re stuck in an authentication loop with the Microsoft Authenticator app. This can be a frustrating situation. Let's work on this together in finding the best possible solution to this problem.
After further research, here are some of the steps you can do to fix this problem
- Reinstall the Authenticator App: Uninstall and then reinstall the Microsoft Authenticator app on your device
- Add a New Sign-in Method: - Log into your Microsoft Office account from a different device (like a laptop), go to the security info section, and add a new sign-in method for the Authenticator
- Check App Updates and Device Settings: Make sure your device requires a PIN or biometric to unlock (lock screen). Try to re-enable face ID or fingerprint in the device settings and restart the device.
Remember, it’s important to keep your account secure, so don’t share your password or security info with anyone.
Let me know if you have any other questions.
Sincerely,
Leonardo_Y
