Thank you for your post and I apologize for the delayed response!
From your issue, I understand that you got a new cell phone and are now locked out of your Azure account due to being unable to complete MFA within the Authenticator app.
Since you assist other organizations through a guest account / guest invitation to their Azure subscription(s), you can ask your customer(s) to see if an Admin within their Azure AD tenant can add additional authentication methods for your user so you can complete MFA. Additionally, they can re-require your user to register for MFA so you can re-add the Authenticator App to your user's profile, or they can invite you again using a different email address.
If the above options don't resolve your issue and this is a lockout scenario, I'd recommend reaching out to our Global Customer Service team, or you can contact the Azure Data Protection team for further assistance in unlocking your Azure AD account (866-807-5850
).
