To activate your account, go to the UC Davis Sona login page.

The Sona site is configured through Central Authentication Service (CAS) Single Sign-On (SSO). You can log into the system using your UC Davis credentials.

Please note that this login system is a new feature as of Winter 2025; if you have used the Sona site for credit before, you should be able to log into your existing account using SSO. Your old user ID and password will no longer be applicable.

If you have any troubles accessing your account, please email the Subject Pool Coordinator.

There is a walk-through of how to use Sona Systems available here: Sona Walk-Through. It will help you figure out how to sign up for and cancel studies, track your credit progress, and reassign credits.
