Duo Two-Factor Authentication (2FA)

Service description

Duo Two-Factor Authentication (2FA) helps protect Odin accounts by adding a second layer of security when you sign in to certain systems, such as PSU's Virtual Private Network (VPN) or Single Sign-On (SSO). SSO is the system that enables you to use your Odin account to access certain university resources through a web browser, such as: Gmail, Banweb, and DataMASTER.

Service details

To access a Duo 2FA-protected system, you must combine your Odin account information with a secondary credential delivered through your phone, mobile device, hardware token, or security key. This prevents anyone else from signing in with your account, even if they know your password.


This service is available to the following groups:

  • Students
  • Faculty
  • Staff
