3D Secure is an authentication protocol designed to reduce fraud and provide extra security to online card transactions. When you shop online at participating merchants, the 3D Secure system verifies your identity before the payment is processed. For Kotak credit cards, this usually involves a Dynamic Passcode (OTP) sent to your registered mobile number or email address. Why Should You Register for 3D Secure?

Follow these simple steps to register:

Step 2: The merchant communicates with Kotak Mahindra Bank to verify if the card is 3D Secure enabled. Step 3: A secure Kotak window appears on your screen. Step 4: You receive an OTP on your registered mobile phone. Step 5: You enter the OTP and click "Submit."
