Enroll in Duo Two Factor Authentication
(Swarthmore login required)

 

Below are a list of the different types of devices that are available for you to use as well as descriptions of each of the ways you can use those devices to authenticate with Duo.

We highly suggest you have at least two devices registered with Duo to provide the most flexibility during login and to insure you will always be able to access your account when needed.

Smartphones/Mobile Phones (Recommended)

Mobile w/ App (Push)

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 gives you the option to Approve or Deny the authentication request.

Mobile w/ App (Passcodes)

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.

Mobile (SMS Passcodes)

SMS passcodes can be requested from the Duo authentication screen upon login. You must have a SMS text capable device already registered with Duo in order 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.

Landline/Mobile Phone (Call Me)

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.
