obtain second order information indicating an order of operations performed by the external device based on the plurality of captured images, and

based on the first order information matching the second order information, authenticate the external device.

2. The electronic apparatus of claim 1 , wherein the at least one processor is further configured to, based on identifying an event related to connection with the external device, transmit an event notification to the external device through the communication interface,

wherein the first order information is generated in the external device based on the reception of the event notification, and

wherein the event related to connection with the external device comprises reception of a beacon signal broadcasted from the external device.

3. The electronic apparatus of claim 1 , wherein the first order information further comprises information related to an order in which a plurality of randomly selected operations are performed by the external device.

4. The electronic apparatus of claim 3 , wherein the first order information further comprises a preset start operation, a plurality of the randomly selected operations, and a preset end operation.

5. The electronic apparatus of claim 1 , wherein the at least one processor is further configured to:

based on the first order information matching the second order information, transmit an authentication success notification to the external device through the communication interface, and

control the communication interface to communicably connect to the external device.

6. The electronic apparatus of claim 1 , wherein the plurality of captured images are first captured images, and

wherein the at least one processor is further configured to:

based on the first order information and the second order information not matching, identify a first operation among the first order information that does not match the second order information,

transmit, through the communication interface, a control command to cause the external device to perform the first operation,

based on the control command being transmitted to the external device, obtain a second captured image comprising the external device through the camera, and

based on identifying that the external device performs the first operation based on the second captured image, authenticate the external device.

7. The electronic apparatus of claim 1 , wherein the plurality of captured images are first captured images, and

wherein the at least one processor is further configured to:

based on the first order information and the second order information not matching, obtain a second captured image comprising the external device through the camera,

obtain third order information indicating an order of operations performed by the external device based on the second captured image,

obtain fourth order information by combining the second order information and the third order information, and

based on the first order information and the fourth order information matching, authenticate the external device.

8. The electronic apparatus of claim 1 , further comprising a display,

wherein the at least one processor is further configured to, based on receiving the first order information through the communication interface, control the display to display a screen regarding capture of the plurality of captured images.

9. The electronic apparatus of claim 1 , further comprising a display,

wherein the at least one processor is further configured to, based on the first order information and the second order information not matching, control the display to display a screen regarding re-capture of a plurality of images of the external device.

10. The electronic apparatus of claim 1 , wherein the first order information further comprises time information related to the performance of a plurality of operations included in the first order information, and

wherein the at least one processor is further configured to identify whether the camera is activated based on the time information.

11. A method of controlling an electronic apparatus configured to communicate with an external device, the method comprising:

receiving, from the external device, first order information comprising an order of operations performed by the external device;

based on receiving the first order information, obtaining a plurality of captured images comprising the external device;

obtaining second order information indicating an order of operations performed by the external device based on the plurality of captured images; and

based on the first order information matching the second order information, authenticating the external device.

12. The method of claim 11 , further comprising:

based on identifying an event related to connection with the external device, transmitting an event notification to the external device,

wherein the first order information is generated in the external device based on the reception of the event notification, and

wherein the event related to connection with the external device comprises reception of a beacon signal broadcasted from the external device.

13. The method of claim 11 , wherein the first order information further comprises information related to an order in which a plurality of randomly selected operations are performed by the external device.

14. The method of claim 13 , wherein the first order information further comprises a preset start operation, a plurality of the randomly selected operations, and a preset end operation.

15. The method of claim 11 , further comprising:

based on the first order information matching the second order information, transmitting an authentication success notification to the external device; and

connecting to the external device.

16. The method of claim 11 , further comprising:

based on the first order information and the second order information not matching, identifying a first operation among the first order information that does not match the second order information;

transmitting a control command to cause the external device to perform the first operation;

based on the control command being transmitted to the external device, obtaining one or more second captured images comprising the external device; and

based on identifying that the external device performs the first operation based on the one or more second captured images, authenticating the external device.

17. The method of claim 11 , further comprising:

based on the first order information and the second order information not matching, obtaining a second captured image comprising the external device,

obtaining third order information indicating an order of operations performed by the external device based on the second captured image,

obtaining fourth order information by combining the second order information and the third order information, and

based on the first order information and the fourth order information matching, authenticating the external device.

18. A non-transitory computer readable medium having instructions stored therein, which when executed by at least one processor cause the at least one processor to execute a method of controlling an electronic apparatus, the method comprising:

receiving, from an external device, first order information comprising an order of operations performed by the external device;

based on receiving the first order information, obtaining a plurality of captured images comprising the external device;

obtaining second order information indicating an order of operations performed by the external device based on the plurality of captured images; and

based on the first order information matching the second order information, authenticating the external device.

19. The non-transitory computer readable medium of claim 18 , wherein the method further comprises:
