permitting, by a server, a first device to join an online meeting held with at least a third device based on receiving a user input from the first device;

permitting, by the server, a second device to join the online meeting in addition to the first device based on receiving login information associated with a user account used by the first device from the second device;

providing, by the server and to at least the third device in the online meeting, screen information of the second device after permitting the second device to join the online meeting;

permitting, by the server, the first device to join an online session based on receiving the login information associated with the user account, wherein the online meeting is held with one or more devices joined in the online session;

providing, by the server, video information captured by a camera of the first device to other devices joined in the online session; and

permitting, by the server, the second device to join the online meeting only if the first device is joined in the online meeting.

2. The method of claim 1 , further comprising:

permitting, by the server, the second device to join the online session based on receiving the login information when the second device is permitted to join the online meeting; and

preventing, by the server, the second device from joining the online session if the online meeting is over, wherein the first device is joined in the online session after the online meeting is over.

3. The method of claim 1 , further comprising:

determining, by the server, that a number of devices associated with the user account that are currently joined in the online meeting is less than a threshold,

wherein permitting the second device to join the online meeting comprises permitting the second device to join the online meeting based on determining that the number of devices associated with the user account is less than the threshold.

4. The method of claim 1 , further comprising:

updating, by the server, a number of devices associated with the user account that are currently joined in the online meeting based on permitting the first device to join the online meeting, and based on permitting the second device to join the online meeting.

5. The method of claim 1 , further comprising:

receiving, by the server, a username and a password from the first device as the login information; and

receiving, by the server, the username and the password from the second device as the login information.

6. A server comprising:

a memory configured to store instructions; and

a processor configured to execute the instructions to:

permit a first device to join an online meeting held with at least a third device based on receiving a user input from the first device;

permit a second device to join the online meeting in addition to the first device based on receiving login information associated with a user account used by the first device from the second device;

provide, to at least the third device in the online meeting, screen information of the second device, after permitting the second device to join the online meeting;

permit the first device to join an online session based on receiving the login information associated with the user account, wherein the online meeting is held with one or more devices joined in the online session;

provide video information captured by a camera of the first device to other devices joined in the online session; and

permit the second device to join the online meeting only if the first device is joined in the online meeting.

7. The server of claim 6 , wherein the processor is further configured to:

permit the second device to join the online session based on receiving the login information when the second device is permitted to join the online meeting; and

prevent the second device from joining the online session if the online meeting is over, wherein the first device is joined in the online session after the online meeting is over.

8. The server of claim 6 , wherein the processor is further configured to:

determine that a number of devices associated with the user account that are currently joined in the online meeting is less than a threshold,

wherein the processor, when permitting the second device to join the online meeting, is configured to permit the second device to join the online meeting based on determining that the number of devices associated with the user account is less than the threshold.

9. The server of claim 6 , wherein the processor is further configured to:

update a number of devices associated with the user account that are currently joined in the online meeting based on permitting the first device to join the online meeting, and based on permitting the second device to join the online meeting.

10. The server of claim 6 , wherein the processor is further configured to:

receive the username and the password from the second device as the login information.

11. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by one or more processors of a server, cause the one or more processors to:

permit a first device to join an online meeting held with at least a third device based on receiving a user input from the first device;

permit a second device to join the online meeting in addition to the first device based on receiving login information associated with a user account used by the first device from the second device;

provide, to at least the third device in the online meeting, screen information of the second device, after permitting the second device to join the online meeting;

permit the first device to join an online session based on receiving the login information associated with the user account, wherein the online meeting is held with one or more devices joined in the online session;

provide video information captured by a camera of the first device to other devices joined in the online session; and

permit the second device to join the online meeting only if the first device is joined in the online meeting.

12. The non-transitory computer-readable medium of claim 11 , wherein the one or more instructions cause the one or more processors to:

permit the second device to join the online session based on receiving the login information when the second device is permitted to join the online meeting; and
