UD CAS: Central Authentication Service

On June 1, 2022 the CAS page will get a new look (shown below). You can identify the new look by the singular log in box with Username or UD ID and Password fields. 

Your access to many UD resources requires you to log in using UD's Central Authentication Service (CAS). Log in using your Username (UDelNet ID, UD ID, or email address) and your UDelNet password.

  • The Username or UDID text box will accept

    • a student or employee's UDelNet ID
    • a student or employee's @udel.edu email address (udelnetid@udel.edu)
    • a student or employee's UD ID
    • an alumnus or alumna's UD ID
    • a non-UD email address associated with a parent/guardian or guest account. 
  • Use your UDelNet password with your Username or UD ID.

  • The Password field will also accept a PIN.
