I am sharing my landline phone number with another person (or persons). Can the landline be registered and used for MFA by more than one person?

FAQ

Yes, provided that you ensure the correct person is answering the authentication phone call. The first person to register the phone number can follow the directions for Landlines in the article, UH Login Multi-Factor Authentication (MFA) - Getting started with your first device.
