American Express SafeKey (AESK) is the authentication service in the American Express card network that uses the 3-D Secure protocol to validate customers at checkout. When you request an authorization using a supported card type and a supported processor, you can include payer authentication data in the request.
Before implementing payer authentication for AESK, contact customer support to have your account configured for this feature.
