MAC ID is a unique, common identifier enabling single sign-on for a number of McMaster systems and applications. Your MAC ID is not your employee or student number.
On February 19, 2013 McMaster upgraded the requirements for MAC ID passwords. Use the online password change tool to change your password to the new, more secure standard.
