Earlier, you were required to register your Standard Chartered Visa/MasterCard Credit/Debit Card for Verified by Visa/MasterCard SecureCode and set a static password that you would then enter for every online transaction on the 3D secure page for authentication. You will now be sent a new 8 digit numeric one time password (OTP) to your registered email address, mobile number every time that you initiate an online transaction. You will need to enter this OTP on the 3D Secure page to authenticate your transaction.
