3D-Secure is the secure protocol designed to ensure enhanced security and strong authentication for consumers when they use their debit or credit cards for online purchases.
It involves the customer being asked by their card issuing bank to enter a passcode or password to prove that they are the legitimate card holder. Card Issuing banks have different methods of generating and delivering these codes.
This process is familiar to customers through the card networks’ brand names, such as Visa Secure and Mastercard Identity Check.
