Overview
Multi-factor authentication is a process where a user is prompted during the sign-in process for an additional form of identification, such as entering a code on their cell phone or providing a fingerprint scan.
Instructions
The instructions below will help walk you through the process of setting up Microsoft Authentication. For additional information, see the links to Microsoft's support page below.
