Abstract: A method and a device for preventing illegal access in an electronic device are provided to obtain an effect to prevent accessing of an illegal user except an authorized user by operating a system protection program for preventing the illegal access when a prohibited key set by the authorized user is inputted. A password checker(106) determines whether a preset prohibited key is found in a password inputted by a user when an event for system access is generated. A controller(100) prohibits the system access of the user and operates a system protection program when the password checker finds the prohibited key. The password checker determines whether the inputted password corresponds to the preset password and determines whether the prohibited key is found in the inputted password if the inputted password does not correspond to the preset password. The password checker generates the password dynamically changed according to time, performs an additional operation for removing the prohibited key when the prohibited key is found in the calculated password, and determines whether the prohibited key is found in the inputted password when the inputted password is different from the additionally operated password.
