MasterCard Secure Authentication

MasterCard SecureCode is an authentication program offered by Mastercard, one of the major payment card networks. It is designed to enhance the security of online credit and debit card transactions, providing an additional layer of authentication for cardholders and merchants.

Here are the key aspects of MasterCard SecureCode:

1. Authentication Process: When a cardholder initiates an online transaction at a participating merchant, MasterCard SecureCode prompts the cardholder to enter a unique password or code to verify their identity. This password or code is known only to the cardholder and the card issuer. The authentication process typically occurs in a secure browser window or through a pop-up on the merchant's website.

2. Two-Factor Authentication: MasterCard SecureCode typically employs a two-factor authentication mechanism. The first factor is something the cardholder knows, which is the unique password or code associated with the card. The second factor is something the cardholder possesses, such as a registered mobile device or a one-time password (OTP) sent to their mobile phone. The combination of these factors adds an extra layer of security, reducing the risk of unauthorized card usage.

3. Card Issuer Involvement: The authentication process of MasterCard SecureCode involves the cardholder's issuing bank or card issuer. The card issuer verifies the cardholder's identity based on the authentication information provided during the process. The issuer then approves or declines the transaction based on the authentication results. This involvement of the issuer helps ensure that the transaction is authorized by the legitimate cardholder.

4. Enhanced Security: MasterCard SecureCode enhances the security of online transactions, protecting cardholders and merchants from fraudulent activities and unauthorized card usage. By adding an additional layer of authentication, it becomes more challenging for fraudsters to make unauthorized transactions using stolen card details. The authentication process helps verify the legitimacy of the cardholder and ensures a more secure online shopping experience.

5. Liability Shift: Similar to other authentication programs, MasterCard SecureCode may include a liability shift feature. If a transaction is authenticated through MasterCard SecureCode, liability for certain types of fraudulent activity may shift from the merchant to the card issuer or payment network. This shift provides added protection for merchants and encourages the adoption of the program.

MasterCard SecureCode is an optional feature for both merchants and cardholders. Merchants need to integrate the MasterCard SecureCode functionality into their online payment processing systems to support the authentication process. Cardholders may need to register their cards for MasterCard SecureCode with their issuing banks to participate in the program.

MasterCard SecureCode aims to provide a secure online shopping experience by preventing unauthorized card usage and reducing the risk of fraud. By leveraging additional authentication measures, it helps protect cardholders and merchants while enhancing the security of online credit and debit card transactions.
