3D Secure (also referred to as 3D secure authentication or 3DS) is a fraud prevention protocol developed by EMVCo to secure card payments by adding an authentication process before making purchases online.

When a payment is processed using the additional security layer of 3DS, the card holder is required to authenticate himself by providing an additional identification key.

By using 3DS, customers gain the trust and confidence they might need to continue with a transaction.
As a merchant, the use of 3DS will protect you from fraudulent costs, since the liability shifts on the issuer’s side!
