Question

Only Global Administrator locked out after losing Microsoft Authenticator access

tobias Horst 0

Hello,

I am the only Global Administrator of a Microsoft 365 Nonprofit tenant.

Unfortunately, I no longer have access to Microsoft Authenticator, which is the only MFA method configured on my administrator account. Because of this, I cannot sign in to the Microsoft 365 Admin Center.

I still have access to:

The domain name

DNS management

The organization's email accounts

What is the correct recovery procedure for a tenant where the only Global Administrator has lost access to the Microsoft Authenticator app and no alternative MFA methods are available?

Any guidance would be appreciated.

Kind regards, Tobias Horst

The first step you need to take is to get the contact number for the country using this Microsoft support document.

Customer service phone numbers – Microsoft Support

Once you have done that, call the number. See the extensive details on how to reach a Human:
