Getting Started With Duo


Registering for Duo

You will be automatically enrolled in Duo during the creation of your Swarthmore account. When you log into your account for the first time you will have to complete the device registration process. You will need to use a laptop or desktop computer plus have a device ready to register in order to complete your device registration and finish your Duo enrollment.

Registering a device is very quick, but please be aware that once you begin the process of registering a device you must finish the process. If you do not finish the process, you will start getting the Duo authorization prompt at login, but will not have a device registered to complete this verification step. There is a general list of available device types listed below, but you can view a more detailed list of devices and how they are used to authenticate here

We strongly recommend you set up at least two devices. You can find more information about how to add more devices to Duo here.

Available Types of Devices


You can use any landline phone to authenticate with Duo. The next time you log in after registering the desired phone number you can choose to have Duo call you to authenticate. You will then receive an automated phone call that will tell you what button to press to approve a login and what button to press to deny it.


Smartphones are the easiest to use and are the recommended device for authentication. If you wish to add a smartphone to Duo, you will put in your number and specify what type of phone it is (iOS, Android, Windows, etc.). You will then be prompted to download the free Duo Mobile App and walked through the process of pairing it to your account. This will allow you to authenticate via push notifications (recommended), a phone call, single-use texted passcodes, or single-use app-generated passcodes.

*If you do not wish to download the app (e.g. if you do not have enough space on your phone) you do not have to. However, this will limit your mobile phone to only authenticate via phone calls or texted passcodes. During setup, when you reach the screen prompting you to download the app, simply hit the “Back” button on the setup page. This will leave your mobile phone registered with Duo, but not force you to pair the app.


You can add the Duo Mobile App to your tablet and pair it to your account in the same way you would for your mobile phone. The setup process will walk you through this as well. This will allow you to authenticate via push notifications and single-use app-generated passcodes.

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