A UD ID (sometimes called a "Student ID" or "EMPLID" [employee ID]) is assigned to each employee, student, or applicant for admission to the University. You can use your UD ID and UDelNet password to log in to secured UD systems. UD is phasing out the use of PINs ("Personal Identification Number" - used by the University as a unique authenticator to validate identity) to log in to secured UD systems.
