DUO Two-Factor Authentication
Duo is a two-factor authentication solution supporting the security of personal and university data for campus community members. Two-factor authentication is a method of confirming your identity using two separate elements: 1) Something you know (your NetID password), and 2) something you have (your registered mobile device or landline phone).
Duo provides an extra layer of security for your NetID, designed so that no one but you can access your account, even if your password becomes compromised. You will be prompted to authenticate through Duo each time you log-in to Duo compatible services.
The service provides multiple options for taking advantage of this additional authentication method, including push notifications through a smartphone app, short codes delivered through the app, or phone calls.
