If the householder agrees to let the visitor go in, the householder instructs the smart phone to generate a password for the visitor to memorize and let the visitor enter the mansion. The password is also sent to a home door machine of the householder. When the visitor an ives the home door machine of the householder, input the password. If the password inputted by the visitor is the same as the password generated by the smart phone, then the home door will open to let the visitor go in.
