What is 3D Secure?
3D Secure (3DS) is an authentication protocol that helps to minimize costly fraudulent transactions by adding an extra layer of protection to the payment journey. After entering credit/debit card details for online transactions, the customer is asked to authenticate their identity using methods such as two-factor authentication (One-Time Passwords) or biometrics (e.g., fingerprints, facial recognition).
