The 3D Secure password is implemented by VISA and MasterCard in partnership with card issuing banks under the "Verified by VISA" and ‘MastercardSecureCode’ services, respectively.
The 3D Secure password adds an additional layer of security through identity verification for your online credit/debit card transactions. This password, which is created by you, is known only to you. This ensures that only you can use your card for online purchases.
You can register for the 3D Secure password for your credit/debit card by visiting your bank’s website.
