Multi-factor authentication provides additional security for your accounts, and many apps and services offer it. Use it whenever it is offered. With multi-factor authentication, anyone trying to log in as you must provide two proofs of ID:
- Something you know, such as your password.
- Something you have, such as a passcode, a phone, or even a mobile app.
Multi-factor authentication for U-M single sign-on is required for faculty, staff, students, and sponsored affiliates. Retirees and alumni are encouraged to turn it on for themselves if it is not already on.
Everyone is encouraged to turn on two-factor with their personal accounts, wherever available. Many popular services and websites, including Facebook and Snapchat, offer two-factor authentication.
Instructions Vary by Service
Multi-factor goes by many different names—such as two-factor verification, two-step verification, login approval, login verification, and so on—but they all protect your information and accounts. See Two Factor Auth (2FA) for more information.
