Abstract: Disclosed herein are a password management apparatus and method, a certification information storage apparatus and a certification information management method. The password management method of accessing and managing desired passwords through a portable password management apparatus and a terminal on which a password management program is installed, includes a first step of executing the password management program on the management terminal, a second step of receiving a user authentication number from the management apparatus, and comparing the first authentication number with a user authentication number previously stored in the management terminal, thereby authenticating whether a user is a legitimate user, and a third step of, only if the user is authenticated as a legitimate user, receiving a password list from the management apparatus and outputting the received password list onto a screen.
