Two-Step Login (Duo) Support

Two-step login — also known as two-factor authentication or two-step verification — provides a second layer of security for any type of login. When you two-step login to a protected service, it combines something you know (your unique Duck ID and password) with something you have (like a smartphone or special hardware token).

UO is using Duo Security for two-step login.
