What is 3D Secure Authentication?
Three-Domain (3D) Secure is a global solution designed to make ecommerce transactions more secure by helping to ensure the transaction is initiated by the rightful owner of the account. The 3D Secure Protocol that 3D Secure is based on serves as the mechanism for cardholder authentication at the time of an e-commerce purchase.
For merchants and issuers, 3D Secure provides an additional layer of security prior to authorisation, creating trust for cardholders they seek when shopping online.
