    Hi @Erard Daniel, Gymnase Bienne Jura bernois, 

    Thank you for posting your question in the Microsoft Q&A forum. I’m here to listen and assist you. To better understand your situation and provide the most accurate guidance, could you please clarify a few details: 

    • I noticed your question is under Microsoft Teams for Education. Can I confirm that you’re using a Microsoft 365 account provided by your school? 
    • Is Microsoft Authenticator installed on your phone and already set up for your school account? 
    • Have you recently changed phones or reinstalled the Authenticator app? 
    • When you try to sign in to Teams, do you see any error messages? Or does the system ask you to approve a code in the Authenticator app, but you’re not receiving any notifications on your phone? 

    Please understand that our initial response may not fully resolve the issue or meet your expectations immediately. If you could share a bit more information on these points, it will help me understand what’s happening and suggest the best next steps for you. 

    Thank you for your patience, I’m looking forward to your reply!

    To log into your Microsoft Teams account using the Authenticator app, follow these steps:

    1. Open Microsoft Teams: Launch the Microsoft Teams app on your device.
    2. Enter your username: Input your email address or username associated with your Microsoft account.
    3. Select Sign In: After entering your username, click on the sign-in button.
    4. Use the Authenticator app: If your organization uses multi-factor authentication (MFA), you may be prompted to verify your identity using the Microsoft Authenticator app.
    5. Check for notifications or codes: Open the Authenticator app on your phone. You should either receive a notification to approve the sign-in or see a verification code.
    6. Enter the code: If you receive a code, enter it in the Teams app to complete the sign-in process.

    If the two-digit codes are not working, consider the following troubleshooting steps:

    • Ensure that you are entering the correct code generated by the Authenticator app.
    • Check if the time on your phone is synchronized correctly, as the codes are time-sensitive.
    • If you continue to experience issues, you may want to try using an alternative sign-in method, such as SMS or a phone call, if available.

    For more detailed guidance on setting up and troubleshooting the Authenticator app, you can refer to the relevant Microsoft documentation.
