I need assistance setting up Microsoft Authenticator on my new phone. My account was previously configured on a phone that I no longer have access to. Unfortunately, I am unable to sign in to update my authentication methods because I am being prompted to approve the sign in through the Authenticator app which is no longer available to me.
