If you do not have access to use your main Multi-Factor Authentication (MFA) verification method (lost phone for example), follow these steps to gain access to the MFA settings page so you can adjust your authentication method.
Open a new browser window in InPrivate or Incognito mode and browse to https://myaccount.microsoft.com/
Using a Private or Incognito mode for your browser prevents any existing credentials from affecting this sign-in event.
You may be asked to login. You will either be asked to enter your NSID@usask account, or it may be listed for you to select.
You will be presented with additional options for accessing your main MFA settings, that include any additional devices or MFA options you set up.
If you do not have any other MFA options, please contact IT Support.
You will now have access to your Multi-Factor Authenticator settings page, where you can change the preferred option, phone number information or set up another device.
