Alternative Methods

  • Manual Migration (if backup/restore fails):

    If the automatic backup and restore process does not work, you may need to manually transfer each account.

    1. On your old device, go to each account in the Microsoft Authenticator app, remove the 2FA, and set it up again on your new device by scanning the QR code.
  • Reconfigure 2FA Directly on Account Websites:

    Some services allow you to log in to your account on their website and reconfigure your 2FA settings to add a new device directly. Follow these general steps:

    1. Log in to the service’s website.
    2. Navigate to the security settings or 2FA section.
    3. Remove the old device and add the new one by scanning the QR code with your new device’s Microsoft Authenticator app.
  • Using a Temporary Phone Number:

    If you have a temporary phone number, you can use it to receive SMS 2FA codes while you are setting up your new device. This is useful if your accounts offer SMS as an alternative 2FA method.

    1. Log in to your account using the temporary phone number to receive the 2FA code.
    2. Update your 2FA settings to add your new device’s Microsoft Authenticator app.
  • Contacting Support:

    If you encounter issues during the migration process, consider contacting the support teams of the respective services. They can guide you through the process of transferring your 2FA to a new device.

General Tips

  • Update Recovery Information:

    Ensure your recovery information (email, phone number) on each account is up to date in case you encounter issues during the migration.

  • Deactivate Old Device:

    Once you have confirmed that all your accounts are working on the new device, it is a good practice to remove the Authenticator app from the old device to prevent any potential security risks.

  • Regular Backups:

    Regularly back up your Microsoft Authenticator settings to the cloud to ensure you have a recent backup in case you need to switch devices again in the future.
