Duo Authentication
SJSU uses DUO for added security when logging in to your SJSUOne account.
Duo provides two-factor authentication which adds a second layer of security to your SJSUOne account by verifying your identity using a second factor provided through the free Duo Mobile app. Find out how to add Duo to your account.
By verifying your identity using a second factor such as your mobile device, others are prevented from logging into your account, even if they know your password. Visit the Duo FAQ page for more information.
