Thank you for posting your question in Micrisoft Q&A.

As per your query you are having issues while logging in to Azure portal with administrator account.

You have registered for MFA in another phone. Now you are trying to register on a new phone and you are getting an error.

This is a normal behavior. Getting MFA registered in multiple phones creates security issues.

To fix your issue, you will have to contact another tenant administrator and get your MFA registration revoked.

To do this you can follow below steps,

• Ask global admin to login to portal.
• Click on Azure Active Directory >> Users >> Authentication methods.
• Click on option "Require re-register multifactor authentication".

Post this when you try to login to portal it will ask you to re-register for MFA. You can now register your MFA using new phone.

If you are the only global admin on the account and are blocked entirely, you can reach out to the Azure Data Protection team to restore access. 866-807-5850

Also, for the future, you can create an emergency access account (break glass) in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) organization because you can't sign in for any reason.
