Central Authentication Service



One of the most important secrets you should keep at UCR is the password portion of your UCR NetID. The campus has moved to a single sign-on environment that will allow you to access virtually all campus computer services with this Net ID.

In the past, applications asked you separately for your UCR Net ID. Thanks to CAS (Central Authentication Services), you can login once per browser session and be able to access multiple applications as long as you don't exit your browser.
