These rules apply for all passwords:

  • Spaces are NOT allowed at the end of a password

What is my Campus ID Number?

Your Campus ID Number is a number assigned to you by SAP. This number used to be a person's Social Security Number (so it was both the student number and used to identify all employees), but as of the 2005-2006 academic year, CMU has moved away from SSN as a primary identifier for security purposes. This SAP-assigned number will be encoded in your campus ID card. To find your Campus ID number, click on My Account in CentralLink, and click the My Profile link. ‚Äč
