Usernames, UDelNet IDs, and UD IDs

Using the UD CAS screen, you can log in to UD secured systems using either a Username (UDelNet ID or email address) or UD ID.


The Username text box on the CAS login page accepts three identifiers to log in to secured UD systems: Use your UDelNet password with your Username.

UDelNet IDs

Students, faculty, and staff can type their UDelNet IDs in the CAS Username text box to log in to secured UD systems.


Your UD ID is a unique 5- or 9-digit number that identifies you, whether you're a student, employee, applicant for admission, UD alumnus or alumna, or former UD student. Every employee, student, or applicant for admission is assigned a UD ID.
