Mastercard SecureCode is a cardholder authentication tool used during online purchases. It adds an extra layer of security by detecting anomalies in transaction, order, and cardholder details. It can also authenticate a transaction by requiring a one-time password or biometric verification before approval.
SecureCode is Mastercard’s implementation of the broader 3D Secure protocol and helps reduce fraud in card-not-present environments. If you accept Mastercard online, enabling SecureCode through 3DS2 helps protect against unauthorized transactions. It can reduce fraud liability, making it a valuable part of your dispute prevention strategy. It’s especially useful for digital goods, subscriptions, and international sales.
