I can't use my Microsoft Authenticator app right now

Question

The problem began when I replaced my old android phone with a new one and since then could not login to my account. I used Samsung smart shift app to move all my apps to my new device, Microsoft Authenticator failed to work on the new device. I tried everything possible, none worked.

I did not loose my account nor my password to the account in question, the main problem lies with  Microsoft authenticator. After I provide my account name & password, the MFA system keeps asking me to approve my login request on Authenticator, which I do not have now. Had the system allowed me to login to my account one more time, I would have removed the MFA (authenticator) from my account. Furthermore, the problem is that I am the admin & no one else has access to this account apart from me.

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. https://docs.microsoft.com/en-us/azure/active-directory/roles/security-emergency-access
