To use Duo, you will need a mobile device (phone/tablet), a landline phone, or a hardware token provided by IT. Our recommended method is to use the Duo app on your mobile device. The app can be downloaded from the App Store or Play Store. Learn more about hardware tokens below. There are also video tutorials on using each authentication method.
Hardware Token
A hardware token is a small device – requiring no network connectivity of any kind – that can be attached to your keychain or slipped into your bag. It generates one-time passcodes on demand, which can be used as your second step during authentication.
If you don't have a phone or would prefer to use a hardware token, visit the help desk in the ETC to speak with a staff member. We'll assign a token to you, walk you through enrollment, as well as your first two-step authentication with your hardware token.
TouchID and Biometric Authentication
Do not use TouchID for the intial setup of your Duo account. Duo will allow you to add TouchID or another biometric authentication method, but this should only be used in addition to a mobile device or hardware token. If used by itself, TouchID will eventually expire and you will be locked out of your account with no way back in.
