NC State University provides a Virtual Private Networking (VPN) Service to all of its students, staff, and faculty members.  The Office of Information Technology requires VPN users to authenticate with Duo Security when logging into the service.  When attempting to connect to the VPN, users will see a Second Password field that will allow them to use a variety of methods to authenticate through Duo.
