Duo | MFA in Email (Desktop, Mobile, Web) and Other Office 365 Products

When to Use?

When Multi-factor Authentication (MFA) has been enabled for your faculty or staff email and other Microsoft 365 products.

  • How often will Duo prompt me to authenticate my email or other Microsoft 365 products?
    • As long as you continue to use your email or other Microsoft 365 products you will have up to 90 days before being asked to log in again. The 90 days will be continuously renewed as as you continue to use the application(s).
    • You will also be asked to re-authenticate when your password changes, expires, or you connect from a new device or browser.
  • What are the other Microsoft 365 products?
    • Word, Excel, PowerPoint Online
    • OneNote Online
    • Office.com
    • Exchange Online (i.e. Email)
    • SharePoint and OneDrive
    • Teams
    • Dynamics CRM Online
    • Azure portal
    • Microsoft 365 Admin portal


Once MFA has been activated, you will be prompted to log back in to your email account on your devices and other Microsoft 365 products. We recommend restarting your computer and mobile devices that are connected to your GVSU email. Duo will then ask you to check your authentication during the launch of your email or other Microsoft 365 products.

Once you launch your email client or other Microsoft 365 products, Duo will ask to verify your identify. If you have configured Duo Push, you will get a push notification. You can also select "Other options" to get a phone call or a passcode.
