obtaining, by the user computing device, the one or more unique IDs of the one or more user computing devices; and

sending, by the user computing device, the correlated relationship between the obtained one or more unique IDs of the one or more user computing devices and the unique ID of the user computing device to the server.

9. The non-transitory, computer-readable medium of claim 7 , wherein the login request to the user account is sent in response to the user computing device accessing a login page, and wherein the network address of the user computing device is obtained by calling a FLASH tool plug-in of the login page with JAVASCRIPT.

10. The non-transitory, computer-readable medium of claim 7 , wherein the received data includes at least a user ID and password of the user account obtained from one or more internet browsers of the one or more user computing devices.

11. The non-transitory, computer-readable medium of claim 7 , wherein the code is a QR code, a bar code, or a text string.

12. The non-transitory, computer-readable medium of claim 7 , wherein the received data corresponding to the login information used by the one or more user computing devices is sent in data cookies.

13. 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:

sending, from a user computing device to a server, a login request for a user account that includes a unique identifier (ID) of the user computing device and a network address of the user computing device;
