I Authenticator

Question

I am not able to use Authenticator so I’m locked out my school and work accounts

Answer 1

Hi Christina

Since your school requires Microsoft Authenticator for MFA, the sign-in process may not offer other verification methods unless they've been configured by the school's IT team. If needed, here's Microsoft's guide for setting up the app: How to add your accounts to Microsoft Authenticator | Microsoft Support 

If Microsoft Authenticator is not sending the approval notification and the authentication number does not appear in your app, please try the following:

• Make sure Microsoft Authenticator is updated and notifications are enabled.
• Check that your device has a stable Internet connection and that the date/time are set automatically.
• If available, select "Sign in another way" and use another verification method.

If no alternative verification method is available, since this is a school account, the MFA settings are managed by your school's IT administrator. Unfortunately, this isn't something that can be reset from the user side.

I'd recommend reaching out to your school's IT administrator and explaining that you're unable to sign in because you're stuck and the Microsoft Authenticator app and are no longer receiving authentication prompts or codes.

You can specifically ask whether they can:

• Reset your MFA settings
• Require MFA re-registration
• Remove your existing Authenticator registration so you can set it up again

You may also want to share the following Microsoft article with them: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | …

If you are unsure who your IT administrator is, you can refer to this official Microsoft guide for assistance: How do I find my Microsoft 365 admin? - Microsoft Support   

Once your IT administrator resets your MFA registration, you should be able to sign in again and go through the Microsoft Authenticator setup process from the beginning, including scanning a new QR code on your device.

I hope this points you in the right direction. If you receive any updates from your IT team or run into any issues along the way, feel free to reply back with more details and I'll be happy to help further.

Best regards,

For work or school accounts, there is no supported workaround if Microsoft Authenticator is required by the organization’s MFA or conditional access policy. If access to the app is lost, the account usually must be recovered through the organization’s IT administrator or help desk so MFA methods can be reset.

Try these self-service checks first:

1. Open Microsoft Authenticator directly and make sure it is unlocked with the device PIN, fingerprint, or Face ID.
2. Make sure notifications are enabled for the app.
3. Make sure the phone has internet access. If needed, switch between Wi-Fi and mobile data.
4. Update Microsoft Authenticator to the latest version.
5. Restart the device.
6. Check that the device date and time are correct.
7. If the sign-in screen offers another verification method, use that instead.
8. If too many sign-in attempts were made, wait and try again later, or use a different MFA method if one is available.

If the device is rooted or jailbroken, work or school accounts in Authenticator are blocked and cannot be used on that device.

If these steps do not restore access, the next step is to contact the school or work IT admin/help desk and ask for the MFA/security info to be reset or for re-registration of Microsoft Authenticator. After access is restored, security methods can be managed in the work or school account security info area.
