The utility model discloses a mobile terminal capable of automatically enciphering. The terminal includes an enciphering module and an automatic modifying module. The enciphering module can be in on state or off state, i.e. if the mobile terminal is started up when the enciphering module is in the on state, passwords must be inputted; and if the mobile terminal is started up when the enciphering module is in the off state, the mobile terminal can be started up normally. The automatic modifying module is connected with the enciphering module.
