A Step-by-Step Guide to Registering Your Devices With Duo

Duo 2-Factor Authentication requires that you have a physical device registered to your account to complete your login process. There are 4 device types that you can register on your own: Mobile Phones, Tablets, Landlines, and U2F Tokens (USB Hardware Token). We highly recommend that you have at least two devices registered to your account, but you can have as many as you feel you need.

For anyone with an iPhone who may be registering your phone with the Duo Mobile app, please make sure you know your AppleID password before you begin the device registration process. While the app is free, you may still be required by the iTunes Store to enter it to complete the app download. 

We are going to follow along with the device registration process, from the very beginning, and you will be able to make selections based on the kinds of devices you may have available. When you self-enroll with Duo or are automatically enrolled by an administrator you will be sent an email by Duo Security. If you were already logged into your email at the time of enrollment you will be able to access and open this email, which will provide you with a link to the device registration page. If you were not already logged into your email, or any other Swarthmore account, you will be brought to the device registration page automatically the next time you log in to a Swarthmore service using your username and password.

 

This is the start screen. Once you click the "Start setup" button you must complete the registration of a device. Duo will ask you for an authentication method the next next time you login it your account, so if you do not finish registering a device you will need to contact the Help Desk to assist you in accessing your account.

 

The next step is to choose what type of device you want to register. These are the four device types mentioned above - Mobile phone (which includes smartphones and other mobile phones), Tablet, Landline, and U2F token.

 

Mobile Phone

Mobile phones are the recommended way of authenticating with Duo to access your account, as they offer the most options. Below are the rest of the set up steps for if you are registering a mobile phone.

 

You will first need to enter the phone number - you do not need to type it with any hyphens or parentheses, just numbers. Please remember to check the small checkbox to indicate that the number is correct. Only once this box has been checked will the "Continue" button highlight for you to move on to the next step.

 

Next you will have to tell it what operating system your phone uses. Most users have iPhones, but this user was registering an Android. If you do not have a smartphone, you will use the the "other" option listed. This step is in preparation for installing the Duo Mobile application (which will take place in the next step), but if you cannot add an application to your phone or you do not want to add an application to your phone, you can also choose the "other" option. This will just mean that you will only be able to receive the automated "Call Me" authentication calls or the SMS text message options for authentication with Duo with that phone.

Please note - BlackBerry has since been removed as an option from this list, as it is no longer a supported operating system.

Once you choose your phone's operating system you will click "Continue."

 

You will next be prompted to download the Duo Mobile app from the app store relevant to your phone's opperating system. Since this user chose Android, the Google Play Store is mentioned in the directions on the screen. If you choose iPhone, the iTunes Store will be mentioned. This shows you exactly what the app is called, what it looks like, and who the developers are to help ensure you are getting the correct app, as there are a few apps out there called Duo (even one by Google!). This is a free app, so you will not be charged for it, but if you are an iPhone user, you may need to know your AppleID password to complete the app download. Please be sure you know this beforehand!

Once you have the app installed, open it on your device. You may have to choose to allow it to send you notifications - that what you want! You may also have to allow it to use your camera. We need that for the next step. On an Android it will let you allow it from inside the app. On an iPhone, you may have to exit the app and go to your Settings app. Scroll down until you see the Duo app icon, tap to open up the settings options, and slide the bar to "on" for allowing access to the camera (it should be the first option). With the Duo app open, and notifications and camera set to "allow," you want to tap "Add Account" in the app. Then, on your computer, click the "I have Duo Mobile installed" button.

 

The next screen on your computer will be a unique QR code, and the screen in the app on your phone will be using your camera. If your phone is laying down on a table or desk, it may look black, but if you've followed along with the step above you should be able to hold your phone up to your computer screen, with the QR code visible. The app will do all the work for you, taking a quick picture of that QR code and pairing your mobile app with your account.

 

If all goes well, a green checkmark will show up over your QR code and a Swarthmore College account will show up on your screen in your Duo Mobile account, with a Key symbol next to it. Tapping that Key symbol will generate you one-time use passcodes!

Tablet

Tablets are another great way of authenticating, and they also use the Duo Mobile app.

First choose what opperating system your tablet uses. Right now, only iOS and Android tablets are supported.

 

You will next be prompted to download the Duo Mobile app from the app store relevant to your tablet's opperating system. Since this user chose Android, the Google Play Store is mentioned in the directions on the screen. If you choose iOS, the iTunes Store will be mentioned. This shows you exactly what the app is called, what it looks like, and who the developers are to help ensure you are getting the correct app, as there are a few apps out there called Duo (even one by Google!). This is a free app, so you will not be charged for it, but if you are an iPhone user, you may need to know your AppleID password to complete the app download. Please be sure you know this beforehand!

Once you have the app installed, open it on your device. You may have to choose to allow it to send you notifications - that what you want! You may also have to allow it to use your camera. We need that for the next step. On an Android it will let you allow it from inside the app. On an iOS tablet, you may have to exit the app and go to your Settings app. Scroll down until you see the Duo app icon, tap to open up the settings options, and slide the bar to "on" for allowing access to the camera (it should be the first option). With the Duo app open, and notifications and camera set to "allow," you want to tap "Add Account" in the app. Then, on your computer, click the "I have Duo Mobile installed" button.

 

The next screen on your computer will be a unique QR code, and the screen in the app on your tablet will be using your camera. If your tablet is laying down on a table or desk, it may look black, but if you've followed along with the step above you should be able to hold your tablet up to your computer screen, with the QR code visible. The app will do all the work for you, taking a quick picture of that QR code and pairing your mobile app with your account.

 

If all goes well, a green checkmark will show up over your QR code and a Swarthmore College account will show up on your screen in your Duo Mobile account, with a Key symbol next to it. Tapping that Key symbol will generate you one-time use passcodes!

Landline

Landlines are great options to have, especialy if you are regularly work out of a single office, or even want to add your home line as a back up in case you might need to work from home. Plus, adding a landline is short and sweet.

You will first need to enter the phone number - you do not need to type it with any hyphens or parentheses, just numbers. Please remember to check the small checkbox to indicate that the number is correct. Only once this box has been checked will the "Continue" button highlight for you to move on to the next step - which for a landline, is the last step!

U2F Token

A U2F Token is a small device designed to be attached to a keychain that plugs into a USB port on a computer. If you have a newer Macbook you would nee to have a USB-C to USB adaptor to use one of these. The brand of U2F token we use here is called Yubikey and you can request from the Help Desk. In order to use one for authentication, you will be required to use the Chrome web browser. In order to even select U2F Token as a device option, you actually need to be using the Chrome web browser, so please check to make sure you are before you begin.

This is just letting you know you are going to get a pop-up window. If you block pop-up windows, you may need to adjust your browser settings, but for the most part you should be fine. You can plug your U2F token into a USB port on your computer at this point. Just make sure you can reach it and that the key symbol is facing up.

 

This is pop-up window you will see. The key symbol on your token should start to flash. Once it does, press your finger lightly over it. The spinning wheel on the pop-up will change to a green check mark when it has been successfully paired and the pop-up will disappear, bringing you right back to the device registration screen. If you are having trouble getting it to recognize that you have tapped the symbol, we have found that having very dry skin can effect how easily it senses being touched. Rubbing your fingers together briefly, or holding your finger fully over the small circle on the U2F token for just a little longer seems to help. 

Note - If the window flashes and a red bar appear across the bottom of the pop-up window, do not be alarmed. Simply try again. If the problem persists, then contact the Help Desk and please let us know of any error messages you may be receiving.

Last Step

You have finished enrolling a device! Your first device is automatically listed as your default device, and also by default they set your account to "Ask me to choose an authentication method." We highly recommend you keep this option selected, as it makes it much easier to switch between devices when you have mutiple devices registered. Duo does not automatically rotate through your devices if you do not respond to your default device! You have to tell it which device you want to authenticate with, so have it automatically sent out a call or a push isn't always convenient.

Now just click "Finish Enrollment" and enjoy your confetti!
