How to enroll in Duo
Chrome, Firefox, Safari, Edge, Opera, and Internet Explorer 8 or later. Some browsers do not support all of Duo’s authentication devices (for example, Security Keys won’t work with Internet Explorer). For the widest compatibility with Duo’s authentication methods, we recommend recent versions of Chrome and Firefox.
Choose Your Authentication Device Type
Select the type of device you’d like to enroll and click Continue.
We recommend using a smartphone for the best experience, but you can also enroll a landline telephone, a security key, or iOS/Android tablets.
Type Your Phone Number
Select your country from the drop-down list and type your phone number. If you’re enrolling a tablet you aren’t prompted to enter a phone number.
Use the number of your smartphone, landline, or cell phone that you’ll have with you when you’re logging in to a Duo-protected service. You can enter an extension if you chose “Landline” in the previous step.
Double-check that you entered it correctly, check the box, and click Continue.
Choose your device’s platform and click Continue.
Install Duo Mobile
Duo Mobile is an app that runs on your smartphone and helps you authenticate quickly and easily. Please follow our instructions, How to install Duo Mobile. After installing our app, return to the enrollment window, and click I have Duo Mobile installed.
You will still be able to log in using a phone call or text message without Duo Mobile, but for the best experience, we recommend that you use Duo Mobile.
Activate Duo Mobile
Activating the app links it to your account so you can use it for authentication.
On iPhone, Android, and Windows Phone activate Duo Mobile by scanning the barcode with the app’s built-in barcode scanner. Follow the platform specific instructions for your device:
Can’t scan the barcode? Click “Email me an activation link instead.”
In Duo Mobile, scan the activation barcode.
The “Continue” button is clickable after you scan the barcode successfully.
Configure Settings & Devices
If this is the device you’ll use most often with Duo then you may want to enable automatic push requests by changing the When I log in: option and changing the setting from “Ask me to choose an authentication method” to “Automatically send this device a Duo Push” or “Automatically call this device” and click Save.
With one of the automatic options enabled Duo automatically sends an authentication request via push notification to the Duo Mobile app on your smartphone or a phone call to your device (depending on your selection).
Your device is ready to approve Duo push authentication requests. Click Send me a Push to give it a try. All you need to do is tap Approve on the Duo login request received at your phone.
