Can you help me add my new phone for the Authenticator app?

To set up your new phone for the Microsoft Authenticator app after losing access to your old device, you will need to follow a few steps. Since you can no longer access your old phone, you will need to revoke the old device from your account and register your new phone. Here’s how you can do that:

1. Contact your IT support: Since you no longer have access to your old device, the best course of action is to reach out to your organization's IT support. They can help you revoke the old device and set up the new one for authentication.
2. Access the Company Portal: If your organization uses Microsoft Intune, you can sign into the Company Portal website or app to find your organization's contact information for support.
3. Set up the Authenticator app on your new phone: Once your old device has been revoked, you can download the Microsoft Authenticator app from the App Store, and follow the prompts to set it up with your work account.
4. Complete MFA setup: You may need to complete multi-factor authentication (MFA) setup using your new device. If your organization has specific requirements, ensure you follow those instructions during setup.

Remember, you may need to verify your identity through other means if you can't access your old device, so having your IT support involved is crucial.
