Multi-Factor Authentication

Updated June 17, 2021

Multi-Factor Authentication (MFA) will be required for Office 365 and Human Resources 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. 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.

Final Deadline June 22, 2021

Everyone will be switched over by June 22, 2021.

To enroll, go to https://MyMFA.uwo.ca. 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.
  • Enter your cell phone number and click the check mark to indicate that the number is correct. (Continue)
  • What type of phone is 519-555-1234? Choose Other (and cell phones).
  • When it returns to the My Settings & Devices screen, choose Add another device (about half way down the screen)

  • Enter your home or office phone number (you can enter an extension for your office phone) and click the check mark to indicate that the number is correct. (Continue)

    • If you choose Call Me and the selected device is your mobile phone, you will need to know how to toggle on the number key pad on your phone so you can press a button when you receive the call.
    • If you choose Enter a Passcode for your Mobile Phone, you will receive a text message. You will receive 10 codes that can each be used once.
    • Note that if your phone is not connected to Wifi and you don't have a texting plan, there will be a charge for the text message.
