Question
How do I log into CAS (Central Authentication Service)?
Overview
CAS, the Central Authentication Service used at UC Davis, provides a single sign-on (SSO) experience for several campus and departmental IT services.
When accessing an application or service, always go to the website intended for the application (ex. canvas.ucdavis.edu, studentaccount.ucdavis.edu). Do not save or bookmark a CAS log in screen as those sessions are limited and will cause issues in the future. Instead, bookmark the page for the service you are trying to access.
Answer
Use your Kerberos Login ID and passphrase to log into CAS.
Staff, faculty, students, or temporary affiliates:
- Forgot your Login ID?
- To retrieve your Login ID, call IT Express at (530) 754 – 4357 between 7:00 AM and 6:00 PM, Monday-Friday.
- Reset your passphrase
- Verify your passphrase
- If you are unsure of what your passphrase is, go to accounts.ucdavis.edu.
- Click Verify Your Passphrase.
New staff, faculty, students, and temporary affiliates, you can create your computing account with these instructions: KB000197 - Create your UC Davis Computer Account.
Applicants, please see our Applicant FAQ at applicant.ucdavis.edu.
If you have left UC Davis, your computing account has closed. You cannot log into any CAS authenticated services.

Beware of Phishing
Sometimes hackers create fake pages that look like the CAS portal page. They do this to try to acquire UC Davis credentials, such as usernames, passwords, and even credit card details. This is called phishing.
Please be mindful of the URL in your web browser when authenticating through the CAS portal page. Also, check for the lock icon to the left of the URL. This is what the CAS login page looks like:
