A smart card security information configuration and recovery system provides a secure Web site and server that allows smart card users to easily create and obtain smart cards and passwords. The client program accesses the smart card inserted into the client computer and retrieves the smart card's ID and other user and system information and sends them to the server which creates an access key. The access key and the smart card ID are stored in the client computer's CMOS or non-volatile memory for boot-up access. The client computer will boot only if the proper smart card is installed or the proper access key is entered when the smart card is unavailable. If the user loses his smart card, then he must gain access to his computer through the access key which the server issues after the user logs in. When the user wants to get a new smart card issued, he logs onto the server which is sent the new smart card's ID that replaces the previous smart card's ID and the server generates a new access key and stores it. The new access key and the smart card's ID are stored in the client computer's CMOS or non-volatile memory for boot access.
