Provided is a system which automatically changes passwords of a door lock in case if passwords inputted from a password input unit do not correspond to the original passwords, and strengthens the security system of the digital door lock by transmitting event information to a preset administrator terminal. The system comprises an administrator terminal which sets a password table composed of data fields in which multiple passwords having different priority by date are stored; acquires the passwords corresponding to a corresponding date from the password table and sets the passwords as valid passwords, changes the valid passwords into next passwords of the corresponding date in response to the reception of an error event, and displays the valid passwords set in response to the confirmation of the passwords; and a door lock which acquires the new passwords corresponding to the corresponding date from the password table and sets the new passwords as authentication passwords; operates a locking device when passwords inputted from an input unit correspond to the authentication passwords; changes the authentication passwords of the corresponding date into the next passwords of the corresponding date when the inputted passwords are different from the authentication passwords; and transmits the error event information to the administrator terminal. |
