Overview
A compatible USB security key provides an alternative to using the Microsoft Authenticator app on a mobile device for multi-factor authentication (MFA) with your Minnesota State Microsoft 365 account.
This option is available to:
- Students who do not have a mobile device that can run Microsoft Authenticator.
- Faculty and staff who do not have a compatible mobile device or prefer not to use their personal mobile device for MFA.
A USB security key is a physical device that plugs into your computer’s USB port to verify your identity when signing in.
Compatible USB Security Keys
Only the two models listed below are supported by our system. Check the exact model before purchasing. Both must be the Bio (FIDO Edition).
Check your computer’s USB ports before ordering. If your computer has a USB-C port, choose the USB-C model—it is the preferred option.
You may purchase a supported model from any retailer; you do not have to use the links above.
Purchasing
Students: If you do not have a mobile device that can run Microsoft Authenticator, you must purchase a compatible USB security key at your own expense.
Faculty and staff: y. Your department must purchase a compatible USB security key using its cost center. Keys may be purchased online or requested through ITS procurement. IT Solutions keeps a limited supply on hand for faster fulfillment, subject to availability. IT Solutions does not cover the cost of security keys, consistent with departmental responsibility for purchasing employee equipment such as computers and monitors.
Set Up
You can set up your security key yourself without having IT Solutions help but if you need help, request MFA assistance or contact the IT Solutions Center.
