If you've changed your phone and are unable to access the Microsoft Authenticator app, you can follow these steps to regain access to your account:
- Use an Alternate Method: Since you mentioned that you received a passcode via email, continue using that method to log in. If you can access your account this way, you can then reset your Multi-Factor Authentication (MFA) settings.
- Reset MFA Settings: If you have access to another admin account, ask them to reset your MFA settings. They can do this by signing into the cloud service portal as an admin and following these steps:
- Go to the user management section for Multi-Factor Authentication.
- Select your account and choose to manage user settings.
- Check the option to require you to provide contact methods again and save the changes.
- Contact Support: If you are still unable to access your account, consider reaching out to Microsoft support for further assistance. They can help you troubleshoot the issue and guide you through the recovery process.
- Check for Blocked Numbers: Ensure that there are no blocked numbers on your device that could prevent receiving verification calls or texts.
- Verify Phone Number: Make sure that the phone number associated with your account is correct and that you have access to it.
By following these steps, you should be able to resolve the circular error and regain access to your account.
