It sounds like you're experiencing an issue with the authenticator app not generating codes, which can indeed create a frustrating loop when trying to sign in. Here are a few troubleshooting steps you can take:
- Check the Clock Settings: Ensure that the clock on your phone is set correctly. If the time is out of sync, it can cause issues with code generation. You may need to disable the "Set Time Automatically" option temporarily to adjust it.
- Restart the App: Close the authenticator app completely and then reopen it to see if it starts generating codes.
- Reinstall the App: If the above steps do not work, consider uninstalling and then reinstalling the authenticator app. Make sure to back up any necessary information before doing this.
- Use Backup Codes: If you have backup codes provided during the setup of MFA, you can use those to sign in instead of relying on the authenticator app.
- Contact Support: If none of these steps resolve the issue, you may need to reach out to your IT administrator or Microsoft support for further assistance.
These steps should help you get out of the loop and regain access to your account.
