Abstract: A system and method include receiving, by an authentication system, device data of a computing device used by a customer during a checkout process of a current transaction on a merchant website and contextual data of the customer. The system and method also include retrieving a customer token associated with a payment instrument of the customer, assigning the computing device a device score and the customer a customer score based on the device data and the contextual data, and computing an overall score from the device score and the customer score. The system and method further include determining from the overall score that the current transaction is not fraudulent before the current transaction is completed and auto-filling payment information of the payment instrument in the customer token during the checkout process of the merchant website to complete the current transaction upon determining that the current transaction is not fraudulent.
