What is Duo Mobile?
Auburn University uses Duo Security for multi-factor authentication (MFA) to verify identity during login using a physical device. The physical device may be a smartphone or tablet using the Duo Mobile app, a text message to a cell phone, an automated voice call to a landline or cell phone, or a Duo hardware token. Users are encouraged to register at least two devices for backup. The Duo Mobile app is the recommended method for multi-factor authentication.

How Do I Set Up Duo Mobile for the First Time?
Duo's self-enrollment process makes it easy to register your phone and install the Duo Mobile application on your smartphone or tablet. Follow the instructions below to set up Duo Mobile:
1. Visit auburn.edu/duo, enter your Auburn username and password, and select Login.
2. From the Duo Security welcome screen, select Get Started.
3. Choose the type of authentication device you would like to enroll. The Duo Mobile Push authentication method is recommended, which pushes a notification to your smartphone when logging into a Duo-protected Auburn resource. While a smartphone is recommended, a cell phone (for SMS text or phone call), landline phone (for phone call), or iOS/Android tablet may also be enrolled. To use Duo Mobile, select "Duo Mobile" as the authentication method.
4. Choose your country code from the list, and enter the phone number you'll use to log into a Duo-protected Auburn resource. Select Continue.
Note: If you chose "Phone number" as the type of authentication device in the previous step, you'll only be able to receive an SMS text code or phone call (not use the Duo Mobile app). If you plan to use Duo Mobile on a tablet (such as an iPad) with no phone service, do not enter a phone number and select I have a tablet instead.
5. Verify that you have entered the correct phone number and select Yes, it's correct.
6. The next screens will prompt you to confirm phone ownership. Select Send me a passcode, enter the verification code from the text message on your phone, and select Verify.
7. If you have chosen the Duo Mobile method, you will see a screen prompting you to download the Duo Mobile app. Install the Duo Mobile app on your phone or tablet from the Google Play Store or Apple App Store. After installing the app, return to the enrollment prompt, and select Next.
8a. If you are activating Duo Mobile from your smartphone device, follow the steps in 8a and pick up with step 9 below: Activating the Duo Mobile app will link it to your account so that you can use it for authentication. After you select "Next" from the previous step, select "Open Duo Mobile" and select "Open". The Duo Mobile app will launch.
Your Duo account will sync, and in the Duo app, you will prompted to change your Account name. This is an optional step; you can simply leave it named "OIT-Information Security" and select Save.
8b. If you are activating Duo Mobile from a separate computer device other than your smartphone, follow these steps in 8b. Activating the Duo Mobile app will link it to your account, allowing you to use it for authentication. From your smartphone, open the Duo Mobile app that you installed, and select "Add +" in the upper-right corner.
Select Use QR code.
Scan the barcode displayed on your computer screen.
Note: If you are not able to scan the QR code, select Get an activation link instead, and enter your email address to send the activation link to yourself. Follow the instructions in the email to activate the new account in Duo Mobile.
Your Duo account will sync, and in the Duo app, you will be prompted to change your Account name. This is an optional step; you can simply leave it named "OIT-Information Security" and select Save.
9. After successfully scanning the barcode and linking your account, you will see confirmation on your screen that Duo Mobile was added. Select Continue.
10. After registering your first Duo authentication method, select "I Don't Want to Add More Devices." You can add more devices later by following the Knowledge Base article: Managing Devices in Duo. It is recommended to add a backup method in case your primary device becomes unavailable.
11. You have now completed the Duo registration process. Click Log in with Duo to receive a test Duo Mobile push.
12. You will automatically receive a push notification on your smartphone if you selected Duo Mobile as your authentication method. If you prefer to authenticate using a different method, you can select "Other options" to view alternative methods.
Select Approve on the Duo push request received on your smartphone as shown below:
13. You'll also see a prompt on your screen to remember your device for future logins up to 7 days. Select "Yes, this is my device" if you're the only person who uses the device.
Note: If you selected to receive phone calls for Duo authentication instead of Duo Mobile, you will receive a phone call and will press 7 to approve the authentication request. The phone number on the caller ID will always be (334) 844-4944, which is the Auburn OIT Service Desk.
You can now log in to a Duo-protected resource with Duo Mobile authentication. If you have any issues setting up or using Duo Mobile, please contact the IT Service Desk at (334) 844-4944.
