Problem: New Phone, Old Authenticator App Not Working

So, you’ve upgraded to a new phone, but your trusty Microsoft Authenticator app isn’t cooperating. Don’t worry; we’ve got you covered! Follow these steps to get back on track:

1. Text Code Login Option

First, check if you have the option to log in using a code texted to your phone. If you do, great! Here’s what you need to do:

  • Visit the Security Info Page: Go to https://mysignins.microsoft.com/security-info in your web browser.

  • Log In: Use the code that was texted to your phone to log in.

  • Remove the Old Authenticator App: Once logged in, find the old Authenticator app and remove it.

  • Add the New Authenticator App: Now, add a new sign-in method using the new Authenticator app on your new phone.

2. No Text Code Login Option

If you don’t have the option to log in using a text code, don’t panic. Follow these steps:

  • Contact Your Office 365 Administrator: Reach out to your Office 365 administrator. Explain the situation and request a reset of your two-factor authentication settings.

  • Verification Process: Your administrator will guide you through the verification process. Be prepared to provide necessary information to prove your identity.

  • Set Up the New Authenticator App: Once your two-factor authentication is reset, set up the new Authenticator app on your new phone.
