Abstract: A system and a method for connecting to an EC(Electronic Commerce) site with an OTP(One-Time Password) are provided to perform authentication by connecting a password module, such as a USB(Universal Serial Bus) or PC card, to a PC, obtaining the available OTP from the password module with a program downloaded from the system, and inserting the OTP into a user ID/password. A password module(100) outputs a password by executing an encoding algorithm when a plain sentence for generating the password is received. A terminal(300) requests authentication to a user authentication server(400) through the network, extracts an OTP from the password module by communicating with the password module through password module operation software downloaded from an EC site, and transmits the extracted OTP to the user authentication server. The password module comprises an interface connected to the terminal in a USB or PCI(Peripheral Component Interconnect) mode, an encoder encoding the extracted OTP, and a key storing part storing public certificate and secret keys.
