3D Secure version 2 is a new and improved secure authentication protocol, which makes several enhancements to the original 3D Secure protocol version 1. Even though 3D Secure 1 provided good security, 3D Secure 2 gives an enhanced cardholder experience and it is updated for payments made using smartphones and wallets (for example Apply Pay, Google Pay or Samsung Pay etc), also leveraging advanced authentication like biometrics.
