Multi-Factor Authentication

Updated April 13, 2021

Multi-Factor Authentication (MFA) will be required for Office 365 by June 22, 2021. Multi‐factor authentication adds a second layer of security, using a secondary device such as your smartphone, to keep your account secure even if your password is compromised. It will be rolled out in phases for different groups or you can opt-in anytime. An email application must support Modern Authentication in order to work with Western's Office 365 email and it is necessary for Multi-Factor Authentication (MFA). The change for Modern Authentication that was rolled out on February 2, 2021 ensures that your Office and email applications already support MFA and Modern Authentication.

Some of you may be using MFA with Office 365 already as you volunteered to be an early adopter prior to the global pandemic which disrupted this project.

Who is affected?

  • There will be three groups switched over on either April 14 or April 28. You will receive a communication from WTS if you are in one of those groups.
  • Timing for other groups will be announced soon and everyone will be switched over by June 22, 2021.
  • You can opt-in anytime.

For details and setup information see https://mfa.uwo.ca.

Setup your Device

Do I Want To Keep it Simple?

If you consider yourself to be technically challenged, you can choose to enroll your cell phone WITHOUT installing the DUO mobile app. Then you can choose to receive a phone call or a text for your secondary authentication. We can get you setup with the App when it's safer to help you in person. You can also enroll your home phone (landline) and receive a phone call for your secondary authentication.

  • Go to https://mymfa.uwo.ca and login.
  • Click the Start Setup button.
  • What type of device are you adding? Choose Mobile Phone.
