Authenticator app

Hi Kira Vera Herren,

Thank you for posting your question in the Microsoft Q&A forum.    

According to your issue, I understand you are unable to get the two-factor authentication (2FA) code from the Microsoft Authenticator app after switching to a new device.  Here are a few suggestions that may help resolve the issue: 

• If you still have access to your previous phone, try opening the Authenticator app there. You may be able to retrieve a verification code or approve the sign-in request.  
• Use an alternative verification method: select “I can’t use my Microsoft Authenticator app right now.” This may allow you to verify your identity via SMS or email, assuming those backup methods were previously set up. 

If the above methods don’t work, since your email is a business account, your university 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 IT team has the ability to adjust or reset your MFA configuration. You can also refer to this Microsoft support article for more information: Manage authentication methods - Microsoft Entra ID | Microsoft Learn 

We hope this helps resolve your issue. Please let us know if you need further assistance.
