Thank you for your post and I apologize for the delayed response!

Since you can't login to your school account using the Authenticator app, you should be able to select the Forgot my password? option during login. However, if you don't have that option or other authentication methods set up, you'll have to contact your school's IT Admin and have them require your account to re-register for MFA, so you can set-up the Authenticator app again.

Forgot Password Steps:
1) If you set up an Authenticator App, you can verify your identity using the code generated within your app. Otherwise, you can select User a different verification option.
2) You can verify your identity via Email, Phone/Text, or Authenticator App. If you don't have access to any of these options, or if you never set this up you can select I don't have any of these.
3) If you have your Recovery codes, you can use them. Otherwise, you can select No.
4) After selecting No, you'll be redirected to fill out the Recover your account form to recover your Microsoft Account. For more info.

If you're using your onmicrosoft.com or tenant specific account, you can still select Forgot my password?, which will take you other authentication methods to login. If none of the above options work, you'll have to reach out to your school's IT department or our Azure Data Protection team for further assistance - (866-807-5850).

For future reference, I'd recommend adding other authentication methods such as phone number or email to prevent being locked out.
