    Hi @Ron German

    If you unable to restore the config of old phone , you should contact the administrator of each application where you use authenticator for MFA to reset your MFA config and enroll your new phone.

    If you are tying to authenticate through Entra ID you can ask you administrator to reset MFA config on your account to be able to enroll your new phone and use it for MFA.
