Problem 2fa authenticator

Copper Contributor


"Hello, I am the Microsoft 365 administrator. I have encountered a problem: I changed my phone and forgot to enable the 2FA feature in the Authenticator on the new phone. Now, I can't access my admin page. Is there a solution to this? Please help me."

Are you the only admin of your tenant? If yes, you are required to raise a support ticket to Microsoft to solve this



To prevent account lockout, it is recommended to have a break glass account that is solely used to access your tenant when no other admin account is able to authenticate or for exigencies. Also, you should have at least three (3) global admin credentials for your tenant.
