General MFA FAQs

MFA helps protect your account by adding an extra step to verify that you are who you say you are when you log on. In addition to your password, your account will be protected by “something you have,” such as a smart phone, mobile phone or a hardware token. This helps prevents hackers from gaining access to your account even if they know your password. 

Hackers will always try to get our passwords, whether through phishing attacks, guessing attacks or by compromising other websites. MFA provides you the peace of mind that, even if your password is compromised, the hackers will not be able to access and use your account to further their attacks. 

All members of the McMaster community, including faculty, staff, and students. 

All McMaster students, faculty and staff are required to implement MFA on their Microsoft services/applications by April 2022. A rolling implementation will begin in January 2022, with information and support to be shared in advance and throughout the winter semester. However, there’s no need to wait! You can start today! McMaster students, faculty and staff can sign up for and use MFA right now. 

There are several options to choose as your second factor:

  • The Microsoft Authenticator smart phone app is the recommended method because of its ease of use and  enhanced security. The app can be configured to use either a push notification (most convenient) or a verification code (most secure). The Microsoft Authenticator app includes additional benefits that you can leverage to protect your personal account. Click here for more information about the Microsoft Authenticator app.
  • A hardware token is a small fob that provides you with a six-digit code that changes every minute and is used as your second factor.
    How to request a hardware token.
  • SMS text messages can be used to send a 6-digit code to your mobile phone, then entering that code at log in as the second factor.
  • Phone calls can be placed to your mobile or office phone to provide you a 6-digit code, then entering that code at log in as the second factor.

The Microsoft Authenticator App is the recommended method for second factor. You can download it by visiting the Microsoft Website here.

After you register for MFA, you will be asked to assert your second factor the first time you log on. You will not be asked to assert your second factor again when you log on from that device and in that location for at least 30 days (for employees) or 90 days (for students). 

The Microsoft Authenticator app software token method does not require an internet connection and does not use cellular data. You can use it even your device is in airplane mode. 

Not necessarily. Your password can still be compromised, and you will need to change it if that happens. We still recommend all the advice that we have always recommended with regards to secure passwords: use a unique and strong password that does not contain any dictionary words and a variety of character sets and continue to be on the lookout for phishing emails. If your password does not get compromised, you will not need to change it.

Password complexity requirement is different from multifactor authentication. You still need to change your MacID password when required if you suspect your MacID has been compromised.
