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

5. The computer-implemented method of claim 1 , further comprising displaying the first application on the first area of the screen after successfully logging into the first application.

6. The computer-implemented method of claim 1 , wherein the first application and the second application include a mobile application and a Web application, and the first user input includes a two-finger pinch gesture on the displayed first application, a predetermined trigger operation on the displayed first application, and a predetermined trigger operation on a virtual or physical button.

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

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

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

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

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

in response to the first user input:

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

displaying at least one icon on a third area of the screen, wherein the third area is outside the second area, the at least one icon includes an icon of a second application, and a user has logged into the second application on the device;

receiving a second user input to drag the displayed icon of the second application from the third area to the second area;

in response to the second user input:

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

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

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

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

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 second application, a user identifier assigned by the server of the second application to the user after the user logged into the second application, and a login certificate sent by the server of the second application after the user logged into the second application.

12. The non-transitory, computer-readable medium of claim 8 , the operations further comprising displaying the first application on the first area of the screen after successfully logging into the first application.

13. The non-transitory, computer-readable medium of claim 8 , wherein the first application and the second application include a mobile application and a Web application, and the first user input includes a two-finger pinch gesture on the displayed first application, a predetermined trigger operation on the displayed first application, and a predetermined trigger operation on a virtual or physical button.

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

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

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

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

in response to the first user input:

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

displaying at least one icon on a third area of the screen, wherein the third area is outside the second area, the at least one icon includes an icon of a second application, and a user has logged into the second application on the device;

receiving a second user input to drag the displayed icon of the second application from the third area to the second area;

in response to the second user input:

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

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

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

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

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

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

19. The system of claim 15 , the operations further comprising displaying the first application on the first area of the screen after successfully logging into the first application.

20. The system of claim 15 , wherein the first application and the second application include a mobile application and a Web application, and the first user input includes a two-finger pinch gesture on the displayed first application, a predetermined trigger operation on the displayed first application, and a predetermined trigger operation on a virtual or physical button.
