Question

I could not login to my Azure account after losing MFA due to a phone change

Hồng Hà Bùi 25

I lost the MFA code in the Authenticator after I changed my phone recently. Now I could not login into my personal Azure Account. My Azure account setup is as below

I have an personal account and I register Azure using that account.
In Azure, I created a tenant, and my account somehow was bound to that tenant (I still see the Default tenant)
I enabled MFA for that tenant account. Now, it looks like every time I login into my personal Azure account, the MFA for that tenant account is required.
I try to access portal.azure.com and switch the tenant to Default, but it also requires MFA code.

Do I have anyway to regain access my personal account?

AI has suggested me to contact other tenant's Admin or enable other verification methods but none of those suggestions are valid because

It's my personal account and I do not have other tenant Admin

I could not enable other verification method now as I am not able to login.
