Locked out of sole Global Admin account (Lost Authenticator). Need alternative verification method for Data Protection Team.

I am the sole Global Administrator for my Azure/M365 tenant. I lost the mobile device that had the Microsoft Authenticator app installed (my only MFA method).

Current Situation:

  • I know my exact password.

I can successfully sign in to the Azure mobile app on my phone without being prompted for MFA.

However, when I try to log in via a web browser (Azure Portal / Admin Center), I am stuck at the MFA prompt asking to approve the request on the lost Authenticator app. There is no "I don't have any of these" option.

The Roadblock with Support: I already opened a support ticket (Case ID: 2609030030002080) and it was escalated to the Data Protection Team. However, the Data Protection Team strictly requires a phone call to verify my identity.

Due to a severe language barrier (English is not my native language), I could not communicate over the phone. I was advised to call my local Microsoft support number, but it is only an automated voice system with no human agent available for Data Protection issues.

My Request: I am completely locked out of my business operations and stuck in a loop. I urgently need a Microsoft moderator to escalate this and arrange an alternative verification method for my Case ID. I am fully willing to verify my identity via:

MS Teams meeting (where I can use Live Translated Captions).

Email/SMS verification codes.

Providing billing, credit card, or business registration documents securely.

Can a Microsoft representative please look into my Case ID and help me bridge this language barrier with the Data Protection Team?I am the sole Global Administrator for my Azure/M365 tenant. I lost the mobile device that had the Microsoft Authenticator app installed (my only MFA method).
