Multi-factor authentication for Office 365
Multi-factor authentication for Office 365 is available to all Winona State University students and employees for securing your access to our primary campus messaging, file storage, collaboration, and productivity system. Once you enable Multi-factor authentication (MFA), you will verify your credentials using a second method only available to you (e.g., respond to a notification sent to your phone) when signing in to your Winona State University Microsoft Office 365 account. MFA is the best way to prevent someone who steals your StarID password from accessing your Office 365 account.
How to enable MFA
Enabling MFA on your Microsoft Office 365 account is a two-step process:
- Turn on MFA in your Office 365 settings and specify your preferred verification method
- Inform the Technical Support Center (TechSupport@winona.edu, 507-457-5240, Somsen Hall 207) that you are ready to use MFA.
Your initial verification options
MFA for Office 365 makes use of your phone to verify your Office 365 credentials. When you first enable MFA, your three verification options are:
Choose this option to receive a one-time password (e.g., a random sequence of digits) via a robocall or text message sent to a phone number you provide. Although this does not need to be a smartphone, the text messaging option does require a compatible phone. Text messages will arrive via your phone's default messaging app (e.g., Apple iMessage).
Choose this option to receive a one-time password via a robocall to the Winona State University office phone assigned to you in the campus directory.
Choose this option to use the Microsoft Authenticator app to approve access. You can decide whether to receive a notification from the app that you can tap to approve access or use one of the rolling, one-time passwords generated by the app. This method allows you to use any device on which the Microsoft Authenticator app is installed. This includes your mobile phone, tablet, or even an Apple Watch.
Personalize your MFA settings
Once you have completed the initial setup, you can edit your MFA settings at any time to:
Add an alternate phone
Add an alternate phone as a verification backup, just in case you cannot access your authentication phone, office phone, or any device with the Microsoft Authenticator app configured. If you enable this option, you will receive a robocall with a one-time password sent to an alternate phone number (e.g., your home phone).
Enable multiple backup verification methods
Enable any of the other verification methods as fail-safes. If your default method fails or is unavailable (e.g., your mobile phone's battery is dead), you can use a different method instead.
Change phone numbers, choose a different verification default, or enable/disable the other verification methods.
Pair or remove Microsoft Authenticator devices
Pair other devices running the Microsoft Authenticator app with your Winona State University Office 365 account or unpair existing devices.
Winona State University Information Technology Services strongly recommends using the Microsoft Authenticator app as your default verification method, while enabling the other three methods as fail-safes. Install the app on any Apple or Android mobile phone or tablet to which you have continuous access and that is connected to the Internet via your cellular data plan and/or WiFi service.
