    To resolve issues with the Microsoft Authenticator app not working with Teams on your new Samsung Android phone, you can follow these steps:

    1. Reinstall the Authenticator App: Make sure you have the latest version of the Microsoft Authenticator app installed. Uninstall it and then reinstall it from the Google Play Store.
    2. Set Up Authenticator Again: After reinstalling, open the app and set it up again. You may need to scan a QR code or enter a setup key provided by your organization or Teams.
    3. Check Account Settings: Ensure that your account is set up correctly in the Authenticator app. You might need to log in to your Microsoft account and verify your identity.
    4. Enable Permissions: Make sure that the Authenticator app has all the necessary permissions enabled in your phone's settings, such as camera access for scanning QR codes.
    5. Contact IT Support: If you are part of an organization, reach out to your IT department for assistance. They may need to reset your account or provide additional setup instructions.

    If you continue to experience issues, it may be related to conditional access policies or password expiration policies that affect shared devices. Ensure that your account complies with these policies.

    Hi Monika,

    I know it's a pain when you can't get into Teams. This usually happens when your old phone's Authenticator app was linked to your account, and the new phone's app isn't set up yet.

    The quickest fix is to re-register your account in the Authenticator app. Just open the app on your new phone, add your work account, and follow the steps. You might need to log into Teams through a web browser to approve it.

    If you don't see the option or it asks for a code you don't have, tell me. Do you have any backup codes or SMS sign-in set up?

    Best,

    Rez
