Account locked

I am the business owner and the only Global Administrator of my Microsoft 365 business tenant. I am completely locked out of my administrator account because Microsoft Authenticator is not working correctly.

When I try to sign in, Microsoft offers only two authentication methods:

1. Approve a request in Microsoft Authenticator.
2. Enter a verification code from Microsoft Authenticator.

Neither method works. The Authenticator app displays an 8-digit code, but Microsoft requests a 6-digit code.

I have no alternative authentication method available, and I cannot access the Microsoft 365 admin centre to reset my MFA settings.

Please escalate this case to the Microsoft Data Protection team for sole Global Administrator account recovery and MFA reset. I can provide the necessary evidence to verify my identity, business ownership and tenant ownership.
