Devices and How They Authenticate

With the Duo Mobile app installed on your mobile device, you can have Duo send push notifications to your device to complete authentication. Opening the push notification will open the Duo app to a screen that allows you to Approve or Deny the authentication request. Push notifications are recommended as they are the most secure.

With the Duo Mobile app installed on your mobile device, you can generate 6-digit, one-time-use passcodes to complete authentication. Open the app on your device and tap the key icon next to your Swarthmore account to generate the code. Once the app is set up with your Duo account, the passcode option will allow you to generate and use passcodes to authenticate even if you are in an area with little to no wifi, data, or cellular service.

NOTE:  in Duo, a "Passcode" is numerical and is NOT the same as your password.

SMS passcodes can be requested from the Duo authentication screen upon login. You must have an SMS text capable device already registered with Duo to use this option. For authentication, choose the “Enter Passcode” option. A blue bar will appear at the bottom of the authentication window with your option to text you a set of 10 one-time-use passcodes. You can then use the passcodes option to enter one of the codes you were sent via text.

NOTE:  in Duo, a "Passcode" is numerical and is NOT the same as your password.

When you register a landline or mobile phone as an authentication device you can receive an automated call to that number to complete authentication. The message will inform you that access has been requested to your account and it will tell you which buttons to press to accept or deny that request.

Duo allows you to register a security key as a second-factor device. This token is a small device designed to carry on a keychain that plugs into a USB port on your computer. One of the security key brands provided by the college is YubiKey. If you have a newer Macbook, you may be required to use a USB-C to USB adaptor to use this option. While on the Duo screen, you will plug in your YubiKey to an available USB port on your computer. The key symbol on the token will begin to blink, and once it does you will touch the key symbol. Once Duo has recognized that the YubiKey has been touched you will be authenticated and given access to your account.
