Abstract

The invention discloses a method and system for management of a dynamic graphic password. The method comprises the steps that a client side generates a total-element dynamic factor list according to dynamic graphic password management strategies from a management server, wherein the dynamic graphic password management strategies comprise a password content strategy, a password format strategy, a password level strategy and a password prompt strategy; and the dynamic graphic password is input into the full-element dynamic factor list according to the dynamic graphic password management strategies. The password management strategies are set for the dynamic graphic password, so that the risk in a high coincidence of the graphic passwords can be controlled effectively; the problem of low safety of the graphic password caused by the too simple dynamic graphic password input by a user can be avoided; a safety level of a dynamic graphic password authentication system can be increased; and further, overall safety and stability of the system can be ensured.
