Multi-Factor Authentication (MFA)

Multi-factor authentication (MFA) requires two steps to verify your identity. Duo is the vendor for MFA.


University System Services 

NDSU employees must use MFA to verify their identity before logging in to the PeopleSoft Finance portal and to access specific information within HRMS Self-Service or Campus Solutions. For these University System services, you need to log in with your University System ID and password as well as your second factor. 

NDSU Services 

Employees and students may be required or have the option to use MFA for NDSU services, including all services that use NDSU CAS (Central Authentication Services), InCommon/eduGAIN and some remote desktop services. If you opt-in for multi-factor for NDSU services, you will use it for most NDSU services, including Office365, Google Apps and Navigate.
