Multi-Factor Authentication

Welcome back! Be sure to visit this site for information & udpates on SDSU Duo MFA.

Multi-factor Authentication (MFA) adds a second layer of security to your SDSUid account. By verifying your identity using a second factor (such as your mobile device or a hardware token), MFA prevents anyone else from logging into your account, even if they know your password. To help keep SDSU users and data safe, the campus utilizes Duo's MFA solution.

Security Tips for Duo MFA

An unexpected MFA request is one you receive that was initiated by someone else trying to sign in as you. This could mean that your SDSUid username and password have been compromised. You should change your password immediately by going through the SDSUid Password change process.

Stay vigilant and only approve MFA requests you initiate yourself, knowingly and intentionally.

Depending on the authentication method, if you suspect you are receiving a fraudulent MFA request, hang up, deny the request, or do not enter the provided passcode. Then, report the fraudulent attempt IMMEDIATELY to [email protected].
