How to Set Up the Microsoft Authenticator App

Overview

Multi-Factor Authentication (MFA) enhances the security of your College account by requiring a second verification step beyond your password. This guide explains how to set up the Microsoft Authenticator App, which is more secure than text/call-based verification. The Microsoft Authenticator is also used with the Self-Service Password Reset Tool.
