Multi-Factor Authentication (MFA), also known as Two-Factor or Two-Step verification, is a security system that verifies a user’s identity by requiring multiple credentials. Rather than only asking for a username and password, MFA requires an additional credential, such as a pin code from a user’s smartphone, approval from a mobile app installed on a user’s smartphone, or a phone call to a specified phone number. ATC employees attempting to access their Office 365 account (email, OneDrive, etc.) from off campus will be required to setup/authenticate using the new security feature.
