Secure protocol 3DS for safe online purchases


I'm a buyer

3D-Secure is the secure protocol designed to ensure enhanced security and strong authentication when you use your debit or credit cards for online purchases. It is called, depending on the card type, “MasterCard SecureCode”, “Verified by Visa” and, in the case of American Express cards, “Safekey”. In the future when you transact, you may be asked to provide a special security code to the card issuing bank in order for the bank to authorise the online transaction when prompted in the PayPal payments page. Card issuing banks have different methods of generating and delivering these codes and so if you don’t know your 3D-Secure passcode or password, and you are not being given the option to enrol online in the bank’s pop up screen, then you will need to contact your bank. Please note that this is not your PayPal account password.

3D-Secure is the secure protocol designed to ensure enhanced security and strong authentication when you use your debit or credit cards for online purchases. It is called, depending on the card type, “MasterCard SecureCode” (soon to be "MasterCard Identity Check"), “Verified by Visa” and, in the case of American Express cards, “Safekey”. In the future when you transact, you may be asked to provide a special security code to the card issuing bank in order for the bank to authorise the online transaction when prompted in the PayPal payments page. Card issuing banks have different methods of generating and delivering these codes and so you should contact your bank if you don't receive your password, or are unsure how to complete this authentication. Please note that this is not your PayPal account password.
