What is MAC ID?

MAC ID is your unique, common identifier, single sign-on for a number of McMaster systems and applications. It is an important step in working together as one University, the creation of a University without boundaries, the enhancement of the student experience and the transformation to a client-centric services delivery model.

This is the first positive step that will benefit the entire University community by allowing us to offer a common authentication mechanism that is the core building block to one sign on for all services we offer you the client resulting in service excellence and the advancement into portal technology.

The MAC ID is a University Technology Services assigned identifier and is not the same as your student or employee number. If you have forgotten your MAC ID, use the Forgot Your MAC ID utility to display your MAC ID or contact the Service Desk for assistance.

Why do I need a MAC ID?

You need a MAC ID for access to services that utilize MAC ID for authentication. As an example McMaster StudentMail and MacMail are services that use MAC ID for authenticating valid email account holders.

What are the benefits/features of having a MAC ID?

  • You have fewer account names and passwords to remember. Use your MAC ID username and password to access a variety of services like email.
  • MAC ID provides individuals with the ability to manage their passwords via the web securely from anywhere. This reduces the need to visit the Service Desk for a password reset.
  • Allows you to set three personal challenge questions which can be used to reset forgotten password at anytime and from anywhere.
  • Utilizes a strong password strength requirement to improve security. To learn more visit Best Practices for Passwords .

Do I have a MAC ID?

Yes, every McMaster employee has a MAC ID. You already have a MAC ID if you use just one of these services:

  • MacSecure
  • Avenue to Learn
  • Central Office Servers (commonly known as AP1)
  • VPN

If you are not sure you have one, use Verify Your MAC ID to check. You will be asked to provide certain types of information. Alternatively you can contact the Service Desk at extension 24357.

Why are Personal Challenge Questions important?

The personal challenge question tool is an important enhancement. Setting up your 3 personal challenge questions will allow you to change your MAC ID password when forgotten. It will save you a trip to the Service Desk for a password reset. Remember to keep confidential your personal challenge questions and answers.

Personal challenge questions may be set in Mosaic.
