New CAS

What is CAS?

The UGA Central Authentication Service, more commonly referred to as CAS, is a trusted way to provide authentication to UGA web applications. CAS authentication is required for many applications provided by UGA.

UGA students, faculty and staff log in to applications protected by CAS with their MyID and password.

There are two versions of CAS. Which version is used will be depend on the UGA web application you are attempting to access.

  • Single sign-on CAS: You enter your MyID and password to authenticate.

CAS 2 Log In Screen

  • Two-factor CAS: You enter your MyID and password. You will then be asked to verify your identity with a device enrolled in ArchPass Duo, UGA’s phone-enabled two-factor authentication service. You can find more information about ArchPass Duo at archpass.uga.edu/enroll

CAS 2 Two-Factor Login

The first time you use two-factor CAS, you will be asked to enroll in ArchPass Duo.

Who Can Use CAS?

CAS allows access to UGA applications for:

  • Admitted and current UGA students
  • Current UGA faculty and staff
  • Guests and affiliates of UGA, under some circumstances

Parents and guardians cannot use CAS to access student information.

Why Do Some Sites Require ArchPass Duo?

Depending on the site, you may be asked to provide a second step for logging in. This may be called two-step or two-factor authentication. At UGA, our two-factor authentication service is called ArchPass Duo.

Two-factor authentication provides an extra layer of security if hackers get your password. 

Adding CAS to Your Applications

Web developers interested in adding CAS to an application must first complete a security review for the application.

To start the security review, complete the CAS/SAML (Gluu) Access Request form and provide basic information about the web application. UGA’s Office of Information Security will contact the requestor to arrange for security testing.

To request access to CAS or Gluu, please complete the CAS/SAML (Gluu) Access Request form.

For technical support transitioning your site for CAS or SAML (Gluu), please submit a Request for CAS/SAML (Gluu) Support.

You can find links to community CAS support and other resources for developers on the CAS FAQs page.
