After installing V-Pro, I enter my username and password, and then the programs requires me to enter the one-time password (OTP). What is it?

The system requires two passwords. The first is a static one and the second is a one-time-password. You can get the latter from the table of numbers which you got after registering to trade online with VCSC (in the form of a paper or plastic card, or sent by email). Please enter four numbers from the card by following the instruction of the program, and then click “Enter”. If you still fail to log in, please contact the Customer Service Department to get a new one-time-password card.
