PROBLEM TO BE SOLVED: To provide a security management system which can secure user's convenience without degrading a level of security.SOLUTION: In a security management system comprising a plurality of authentication devices, when a second authentication device receives authentication request from a user, an authentication method to be applied to user authentication in the second authentication device is determined on the basis of an authentication method which is applied to user authentication in a first authentication device and has already succeeded in the user authentication of the user (S4 and S5). The second authentication device performs the user authentication by reading out user information required for the determined authentication method (S6). When the user authentication in the second authentication device is successful, the authentication method applied to the user authentication is stored in a server (S7 and S8). |
