4. The computer-implemented method of claim 1 , wherein the login authorization information includes at least one of an application identifier of the first application, a user identifier assigned by the server of the first application to the user after the user logged into the first application, and a login certificate sent by the server of the first application after the user logged into the first application.

5. The computer-implemented method of claim 1 , further comprising displaying the second application on a third area of the screen after successfully logging into the second application, wherein the second area is smaller than the third area.

6. The computer-implemented method of claim 1 , further comprising:

receiving a second user input to drag an object displayed in the second application, displayed on the second area of the screen, to the displayed icon of the first application; and

in response to the second user input, transmitting the object to the first application for further processing of the object.

7. The computer-implemented method of claim 1 , wherein before receiving the user input, the method further comprises:

receiving a third user input to zoom out the second application, wherein the second application is displayed on a third area of the screen of the device before receiving the third user input; and

in response to the third user input:

zooming out the second application, wherein the second application is displayed on the second area of the screen after zooming out the second application, and the second area is smaller than the third area; and

displaying at least one icon on the first area of the screen, wherein the at least one icon includes the icon of the first application.

8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

receiving a user input to drag a displayed icon of a first application from a first area to a second area of a screen of a device, wherein a second application is displayed on the second area of the screen, the first area is outside the second area, and a user has logged into the first application on the device;

in response to the user input:

transmitting login authorization information of the first application to the second application; and

submitting, by the second application, the login authorization information to a server of the first application through a server of the second application; and

authorizing logging into the second application on the device in response to receiving a notification from the server of the first application through the server of the second application, wherein the notification indicates that the login authorization information is verified.

9. The non-transitory, computer-readable medium of claim 8 , wherein the second application is not logged into by the user on the device when receiving the user input, and the server of the first application is used for login authorization verification.

10. The non-transitory, computer-readable medium of claim 8 , wherein an association between the first application and the second application has been pre-established before receiving the user input, and the first application and the second application include a mobile application and a Web application.

11. The non-transitory, computer-readable medium of claim 8 , wherein the login authorization information includes at least one of an application identifier of the first application, a user identifier assigned by the server of the first application to the user after the user logged into the first application, and a login certificate sent by the server of the first application after the user logged into the first application.

12. The non-transitory, computer-readable medium of claim 8 , the operations further comprising displaying the second application on a third area of the screen after successfully logging into the second application, wherein the second area is smaller than the third area.

13. The non-transitory, computer-readable medium of claim 8 , the operations further comprising:

receiving a second user input to drag an object displayed in the second application, displayed on the second area of the screen, to the displayed icon of the first application; and

in response to the second user input, transmitting the object to the first application for further processing of the object.

14. The non-transitory, computer-readable medium of claim 8 , wherein before receiving the user input, the operations further comprises:

receiving a third user input to zoom out the second application, wherein the second application is displayed on a third area of the screen of the device before receiving the third user input; and

in response to the third user input:

zooming out the second application, wherein the second application is displayed on the second area of the screen after zooming out the second application, and the second area is smaller than the third area; and

displaying at least one icon on the first area of the screen, wherein the at least one icon includes the icon of the first application.

15. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:

receiving a user input to drag a displayed icon of a first application from a first area to a second area of a screen of a device, wherein a second application is displayed on the second area of the screen, the first area is outside the second area, and a user has logged into the first application on the device;

in response to the user input:

transmitting login authorization information of the first application to the second application; and

submitting, by the second application, the login authorization information to a server of the first application through a server of the second application; and

authorizing logging into the second application on the device in response to receiving a notification from the server of the first application through the server of the second application, wherein the notification indicates that the login authorization information is verified.

16. The computer-implemented system of claim 15 , wherein the second application is not logged into by the user on the device when receiving the user input, and the server of the first application is used for login authorization verification.

17. The computer-implemented system of claim 15 , wherein an association between the first application and the second application has been pre-established before receiving the user input, and the first application and the second application include a mobile application and a Web application.

18. The computer-implemented system of claim 15 , wherein the login authorization information includes at least one of an application identifier of the first application, a user identifier assigned by the server of the first application to the user after the user logged into the first application, and a login certificate sent by the server of the first application after the user logged into the first application.

19. The computer-implemented system of claim 15 , the operations further comprising displaying the second application on a third area of the screen after successfully logging into the second application, wherein the second area is smaller than the third area.

20. The computer-implemented system of claim 15 , the operations further comprising:

receiving a second user input to drag an object displayed in the second application, displayed on the second area of the screen, to the displayed icon of the first application; and

in response to the second user input, transmitting the object to the first application for further processing of the object.
