Lost access to Azure MFA, although I have my Microsoft account MFA

I can sign in to my personal Microsoft account and its MFA works normally. However, I am unable to sign in to Azure because Azure is requesting an MFA verification through Microsoft Authenticator that was registered on a phone I no longer have.

The affected personal Microsoft account is ******@gmail.com.

My Microsoft account itself is accessible and I can complete its normal MFA verification. The problem is specifically with the MFA configured for Azure / Microsoft Entra ID. I no longer have access to the phone containing the Authenticator registration, and I have no other MFA method available for the Azure sign-in.

As a result, I am completely locked out of my Azure resources and cannot access the Azure Portal to change or reset the Azure MFA configuration.

I need assistance recovering access to Azure, ideally by resetting the Azure/Entra MFA registration so that I can register Microsoft Authenticator on my current phone.

I can provide any information necessary to verify ownership of the Azure subscription/tenant and the account.

    The key question is whether another administrator can still access the affected Azure directory.

    If another administrator has the necessary permissions, they can review your account under Entra ID → Users → your user → Authentication methods and arrange MFA re-registration. The administrator’s required role depends on whether your account also holds administrative roles.

    Could you confirm:

    1. Are you the only Global Administrator in this directory?
    2. Is your Gmail-backed Microsoft account a member or guest in the affected directory, if you know?

    Those details will help distinguish administrator-assisted recovery from a tenant lockout requiring Microsoft Support. Please keep ownership documents and verification details out of the public thread.
