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.
