Dear Thomson, Eleanor
Thank you for posting your question in the Microsoft Q&A forum.
We understand you're experiencing a frustrating loop when trying to log in using the Microsoft Authenticator app. Here are a few suggestions that may help:
- Check if you still have access to your old phone – If so, try opening the Authenticator app there to retrieve the code or approve the sign-in request.
- Use an alternative verification method – In the second image you provided, try selecting “I can’t use my Microsoft Authenticator app right now”. This should allow you to verify via SMS or email, assuming those options were set up previously.
If the above methods don’t work, since your email is associated with a university account, your institution’s IT team or Helpdesk may be able to reset your Multi-Factor Authentication (MFA) settings. This will allow you to reconfigure MFA from scratch on your new device. As general Microsoft Support, we do not have administrative access to change these settings. Only your university’s IT team has the ability to adjust or reset your MFA configuration.
