Customers can use Kount Access to generate a Device ID for each login. If the Device ID is the same as the previous login, the end user is allowed to pass through to the site. If the ID is different or missing, force Two-Factor Authentication. End Users should be notified that clearing their browsing data or using private browsing my force Two-Factor Authentication.
The customer should implement Kount Access on their login page. All API requests for device, velocity, and decision will include the Device ID. Store the Device ID (or multiple Device IDs since one customer may have multiple devices) with the User Account.
