Multifactor Authentication (MFA) for TMU Microsoft accounts and Office 365

Multi-factor authentication (MFA) is a security control that adds an additional layer of security to protect your online account. If you’ve been prompted to set up MFA on your Microsoft Office 365 account, this page will guide you through the process.

Unlock Multi-Factor Authentication (MFA)

If you see the message "Your sign-in was successful but you don't have permission to access this resource"

Means you either have no access to the resource or you did not set up your MFA.

To check and activate MS MFA for your account:

1. Log into the my.torontomu.ca portal with your username and password.
2. In the Self Service box, select Personal Account.
3. Find the Security section, select Microsoft Multi-Factor Authentication.
4. From here, select Proceed to Microsoft MFA Setup and your Microsoft account will automatically be reactivated.

Note: If you continue to see an error message, sign out and sign back into your Microsoft account.

First time setup using Microsoft Authenticator

Open your preferred Internet browser and visit https://portal.office.com/ (external link)  to initialize MFA process.

1. When prompted for a username on the Microsoft sign-in page, please enter your TMU email address.

 

2. Enter your my.torontomu password.

3. On the “Keep your account secure” screen, you can begin setting up MFA.

You’ll have the option of generating authentication codes using the Microsoft or Google Authenticator apps.

Add/remove as needed,

It is recommended to have at least the following methods:

  • Password (required)
  • Microsoft Authenticator
  • Device linked Passkey

Make sure to have at least two additional authenticathon methods in addition to Password.

Some versions of Microsoft authenticator require login. The second authenticator might be required to avoid a catch-22 situation that requires MFA to login to Microsoft authenticator using the same authenticator.

If you’re planning to get a new phone or device or reinstall the Authenticator App, make sure to backup your accounts.
