The 3D Secure password is an additional password that you’ll be asked to enter after entering your card details on the payment page. You’ll be redirected to your individual bank’s page where you'll have to enter the Verified by Visa password for Visa cards or SecureCode password for MasterCard cards. Your card-issuing bank will give this password to you and you should have this password prior to shopping on Nykaa.
Note: 3-D secure password has been made mandatory by the Reserve Bank of India to ensure safer online shopping. This will add an additional layer of security and thus, prevent misuse of a lost or stolen card, as the user will be unable to proceed unless they enter the password associated with your card, created by yourself and known only to you.
