In order to use Duo Mobile for authentication to protected applications, it needs to be activated to link a user's mobile device to their Duo account. The easiest method of Duo Mobile activation is available right from the Duo Prompt. End-users can activate Duo Mobile for the first time by installing the Duo Mobile app and tapping Add Account or “+” in the main account list to add a new account. An on-screen QR code will appear in the Duo Prompt that they can scan with their device.
What if you can't scan the QR code?
If the camera on the device is not working or if the end-user is authenticating to an application that does not display the Duo Prompt, then they will not be able to access the QR code for activation. In these situations, an administrator can help them activate their device using the Admin Panel. An activation link can be sent to the end user via SMS or by generating an activation URL that can be copied and pasted into an email that the user can access from their device. Using this method allows the end-user to activate Duo Mobile without a QR code.
