The DUO mobile app and hardware tokens used by NDSU as part of its 2 factor authentication process are encryption items that are subject to export control regulations.  NDSU’s export control office has determined that the DUO app and hardware tokens themselves are controlled to Cuba, Iran, North Korea, Sudan, Syria and the Crimea Region of Ukraine. If you travel to one of these countries you must delete the DUO Mobile app from any device you take with you. Also, you cannot take a DUO hardware token with you. While in one of these countries use a phone call or passcode retrieved via SMS to authenticate with the Two-Step Login.  Contact the Export Control office with questions or to see if a license exception is available for the specific country you will be visiting.
