         [0096]    When the reception is completed in step S 56 , the second electronic device changes from the soft AP mode back to the general station mode in step S 57 . Subsequently, after the cancellation of the access to the first electronic device, the second electronic device may access the access point connected to the main server in step S 58 . 
         [0097]    As such, the second electronic device may change to the soft AP mode having present AP information through various operations and receive, from the first electronic device, the access point information to connect to the main server and preset authentication information in the soft AP mode. 
         [0098]    As described above, when there is a first electronic device  100  that has completed an access to the main server  10  and user authentication and a new electronic device, i.e., a second electronic device  200 , which has not completed the access to the main server  10  and user authentication, is added, the smart home according to an embodiment may enable the first electronic device to transmit information on an access to the main server  10  and authentication information for user authentication to the second electronic device. 
         [0099]    Thus, when the second electronic device  200  is added, the smart home  1  according to an embodiment may prevent the second electronic device  200  from separately performing cumbersome procedures for an access to the main server  10  and user authentication. 
         [0100]    Therefore, the smart home  1  according to an embodiment may simplify access and authentication processes occurring whenever an electronic device supporting a new smart home service is added. Thus, the smart home  1  according to an embodiment may provide a smart home providing remarkably improved user convenience that may more easily implement a process of accessing a main server and a user authentication process whenever electronic devices are added. 
         [0101]    Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that may fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
