The University of Nebraska and the Nebraska State College Systems (except UNMC) use a common Student, Faculty and Staff ID number known as the NUID—Nebraska Unique ID. This process will allow you to claim it by creating a TrueYou password. The combination of your NUID and TrueYou password is referred to as your TrueYou account.
