With the Duo Mobile app installed on your tablet or app-enabled touchscreen device (such as an iPod Touch), 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. |

Duo allows you to register a U2F Token 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. We use a U2F token called a YubiKey, but all U2F tokens require the use of the Chrome web browser and access to a USB port to functionOne 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. If you have previously registered a security key with Duo it may have only been compatible with the Chrome browser. If so, the next time you authenticate with your security key you may get a prompt titled "Let's Update Your Security Key". This update will enable you to use your security key in more browsers.

There is another hardware token option available called a passcode generator (or digipass token). This is a small device designed to carry on a keychain that generates a 6-digit one-time use passcode when you push the green button on the device. These tokens need to be registered to you by the Help Desk. While on the Duo screen during login, you can click on the "Enter a Passcode" button - even if you did not select the token from the device dropdown menu. Anywhere that offers the "Enter a Passcode" option will accept a passcode from any registered device of yours that generates a passcode, including your digipass token. Once you enter the passcode, click the "log in" button and you will be given access to your account. NOTE: in Duo, a "Passcode" is numerical and is NOT the same as your password. |
