in response to the allowance of the registration of the second device with the server, registering the second device with the server by transmitting identification information of the second device from the first device to the server, and storing the identification information of the second device in the server;

wherein the first device and the second device are disposed within at least one network connected to the server.

2. The method of claim 1 , wherein the identification information comprises at least one of a unique number of the second device, a product name of the second device, and a serial number of the second device.

3. The method of claim 1 , further comprising:

searching for the second device in the at least one network by the first device.

4. The method of claim 1 , further comprising:

connecting the first device to the second device and activating the second device.

5. The method of claim 1 , further comprising:

receiving an inquiry about a password at the first device from the second device, when the first device connects to the second device.

6. The method of claim 1 , further comprising:

receiving the identification information of the second device at the first device from the second device.

7. The method of claim 1 , further comprising:

receiving a setting that limits a connection of the second device at the first device.

8. The method of claim 1 , further comprising:

registering the first device in the server.

9. The method of claim 8 , further comprising:

generating an account of the first device in the server after registration of the first device in the server, and connecting a plurality of devices to the account.

10. The method of claim 1 , further comprising:

receiving an inquiry about a password at the first device from the second device.

11. The method of claim 10 , further comprising:

15. A device comprising:

a communication unit; and

a controller that connects the communication unit to a server, sends a message related to registration of another device with the server to the other device, receives data indicating allowance of the registration from the other device, and, in response to the allowance of the registration of the other device with the server, transmits identification information of the other device to the server through the communication unit so that the other device is registered in the server;

wherein the device and the other device are disposed within at least one network connected to the server.

16. The device of claim 15 , further comprising:

a storage unit that stores the identification information of the other device.

17. The device of claim 15 , wherein the identification information comprises at least one of a unique number of the other device, a product name of the other device, and a serial number of the other device.

18. The device of claim 15 , wherein the controller controls registration of the other device in the server.

19. The device of claim 15 , wherein the controller controls reception of an inquiry about a password from the other device when the device connects to the other device.

20. The device of claim 19 , wherein the controller controls transmission of the password from the device to the other device.
