UTS Service Catalog

Your MacID is your user name, a unique, common identifier enabling single sign-on for a number of McMaster systems and applications. Your MacID is not your employee or student number. If you are unsure if you have a macid, it is generally, the first part of your email address before the @ symbol.


You are required to change your MacID password every year. Changing your password requires that you clear the saved passwords on your computer. Please see the Clearing Saved MacID Password Guide for instructions. Your MacID password is yours to keep secure. Do not share it with anyone.
