3-D Secure (3DS / EMV 3DS)
3-D Secure is an EMVCo messaging protocol that adds cardholder authentication to card-not-present payments, sharing risk data between the merchant, the card network, and the issuer across three domains. The modern version, EMV 3DS (3DS2), supports frictionless risk-based authentication and app/biometric challenges, and is the primary mechanism card payments use to meet Strong Customer Authentication requirements. It is branded as Visa Secure, Mastercard Identity Check, and others.
Also known as 3D Secure, 3DS, 3DS2, EMV 3DS, Verified by Visa, Mastercard Identity Check.
