Duo multi-factor authentication is a system that requires a second piece of information or “factor” (such as a temporary code that is created for you) before you can log in to a site or service. Using multi-factor authentication improves privacy and security.
To log in to a site or service protected by multi-factor authentication (variants are known as two-factor or two-step), you need your usual password and username, plus something that only you have, such as a token or smartphone. Duo uses that device to deliver the second factor. Specifically, Duo generates a second, temporary password and sends it to you, typically by using your smartphone or token.
