AMEX SafeKey

AMEX SafeKey is a security feature implemented by American Express as a part of the 3D Secure protocol, which enhances the safety of online transactions. This technology helps prevent unauthorized use of an American Express card by verifying the cardholder's identity through additional security measures during online purchases. When a transaction is initiated, SafeKey may prompt the cardholder to enter a password or a dynamic code sent to their mobile device, effectively adding an extra layer of security. This verification process helps ensure that the person making the online purchase is indeed the cardholder, thereby reducing the risk of fraud and enhancing the overall security of online shopping.
