I’m locked out of a Microsoft Entra tenant where I am the only Global Administrator.
The tenant was created via Partner Center, and the admin account is a guest (#ext#) user.
After Microsoft’s migration from legacy MFA to the new unified Authentication Methods policy,
the admin account can no longer complete MFA.
As a result, I cannot:
- Access admin.microsoft.com
- Re-register Microsoft Authenticator
- Repair authentication methods
There is no other Global Administrator available.
How can I get access to my account again?
