Multi-Factor Authentication - Using MFA

Multi-factor authentication is used as an additional layer of security to protect the confidentiality of private data. All NDSU students, faculty and staff are responsible for protecting private and restricted data, including data subject to export control regulations, FERPA, PCI and other pertinent state and federal laws and industry regulations.

Using Multi-factor Authentication 

Do not approve DUO prompt if you are not currently expecting one. If you receive a DUO prompt that you did not initiate, deny the prompt and mark it as fraud. Change your password for all accounts that use that password. For instructions on resetting your NDSU and NDUS passwords, visit If you have any questions, please contact the IT Help Desk at 701-231-8685.

Remember Me Option 

You can choose to reduce the need to MFA if you select the checkbox that says "Remember Me for 30 Days" (or for 10 hours in PeopleSoft applications or 60 days in Office365). This will work if you sign in to the same device and browser regularly. If you use a public device, do not choose this option. Managed computers on campus (including instructor workstations in classrooms) are reset every night, so this option will not work.
