receiving the login key by the terminal; and

displaying the content on the terminal mounted to the head-mounted device.

4. The method according to claim 1 , further comprising:

receiving the login key by the terminal; and

displaying the content on the terminal mounted to the head-mounted device.

5. The method according to claim 1 , further comprising:

receiving the login key by the head-mounted device, and

displaying the content on the head-mounted device.

6. The method according to claim 1 , wherein the receiving of the input of the user identification information comprises receiving input of the user identification information before the head-mounted device is worn by the user.

7. The method of claim 1 further comprising displaying a first prompt on the terminal prompting a user to activate the head-mounted device in response to receiving the login key.

8. A system for providing content, the system comprising:

a memory; and

a processor connected to the memory, wherein the processor is configured to execute instructions stored on the memory for:

while in a normal mode, the normal mode corresponding to a terminal being separated from a head-mounted-device:

generating instruction for displaying a user interface for allowing logging in to a first service on a terminal;

generating user identification information in response to an input by a user of a user ID and a password to the user interface, wherein the user identification information associates the user with a first application;

transmitting the user identification information to a server;

receiving a login key for logging in to the first service in response to authentication of the user identification information by the server;

prompting the user to insert the terminal into the head-mounted device in response to successful authentication;

switching an operating mode of the terminal from the normal mode to a head-mounted device (HMD) mode;

while in the HMD mode, the HMD mode corresponding to the terminal being mounted to the head-mounted device:

transmitting the login key to the server;

receiving content from the server, following successful authentication using the login key, wherein the content is viewable on the head-mounted device.

9. The system according to claim 8 , wherein the processor is further configured to execute the instructions for:

transmitting an issuance request for the login key to the server in response to the input by a user to the user interface; and

receiving the login key from the server.

10. The system according to claim 8 , wherein the processor is further configured to execute the instructions for:

receiving the login key by the terminal; and

displaying the content on the terminal mounted to the head-mounted device.

11. The system according to claim 8 , wherein the processor is further configured to execute the instructions for:

receiving the login key by the head-mounted device, and

displaying the content by the head-mounted device.

12. The system according to claim 8 , wherein the processor is further configured to execute the instructions for: receiving of the input of the user identification information comprises receiving input of the user identification information before the head-mounted device is worn by the user.

13. The system according to claim 8 , wherein the processor is further configured to execute the instructions for:

displaying the content by the terminal mounted to the head-mounted device.

14. The system of claim 8 , wherein the processor is configured to execute instructions stored on the memory for displaying a first prompt on the terminal prompting a user to connect the terminal to the a head-mounted device in response to the input by the user to the user interface.

15. A content display device, comprising:

a head-mounted display device;

a memory; and

a processor connected to the memory, wherein the processor is configured to execute instructions stored on the memory for:

while in a normal mode, the normal mode corresponding to a terminal being separated from the head-mounted-device:

generating instruction for displaying a user interface for allowing logging in to a first service on a terminal;

generating user identification information in response to an input by a user to the user interface, wherein the user identification information associates the user with a first application;

transmitting the user identification information to a server;

receiving a login key for logging in to the first service in response to authentication of the user identification information by the server;

switching an operating mode of the terminal from the normal mode to a head-mounted device (HMD) mode;

while in the HMD mode, the HMD mode corresponding to the terminal being mounted to the head-mounted device:

transmitting the login key to the server; and

receiving content from the server following successful authentication using the login key, wherein the content is viewable on the head-mounted display device.

16. The content display device according to claim 15 , wherein the processor is further configured to execute the instructions for:

transmitting an issuance request for the login key to the server in response to the input by a user to the user interface; and

receiving the login key from the server.
