PROBLEM TO BE SOLVED: To provide a log-in authenticating method of a user utilizing a business system and a commercial service system, capable of reducing the communication, and allowing a plurality of persons to simultaneously use the service by one account. SOLUTION: The business system creates a password list prior to authentication, and transmits the list to a commercial service system. When the request for using the commercial service system 2 is transmitted from a client utilized by a user to the business system, the business system receiving the request for use checks the user's commercial service using authority, and selects one password from the password list to return the password to the client. The client transmits the returned password to the commercial service system, and the commercial service system compares the password with the password in the account information (password list), permits the log-in when they are agreed with each other, and defeats the used password.
