Duo Authenication

How does Duo 2FA work?

Two-Factor Authentication combines something you know (your username and password) with something you carry (via an app on your smartphone) to ensure that only you can log in to your SJSUOne account. After entering your username and password you will be prompted to confirm your login using your device.

Who should use Duo 2FA?

All SJSU Staff and Faculty accounts are now protected by Duo. It is our goal to have all SJSU students protected with Duo by the end of May, 2021.
