determining, by the server, whether the received second verification code matches the verification code; and

in response to determining that the received second verification code matches the verification code:

verifying, by the server, the first device; and

authorizing, by the server, the application login on the first device.

6. The computer-implemented method of claim 1 , wherein the audio signal further includes a device identifier of the second device.

7. The computer-implemented method of claim 1 , wherein the first message is transmitted by the server to the second device through an authorized channel between the server and the second device, and the audio signal is broadcasted by the second device based on near-field acoustic communication.

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

receiving, by a server and from a first device, a login request, wherein the login request includes login information used for an application login;

in response to receiving the login request from the first device, transmitting, by the server and to a second device different from the first device, a first message including a verification code, wherein the first message instructs the second device to broadcast an audio signal including the verification code, and the verification code is used to verify the first device by the server;

determining, by the second device, whether the first device senses the audio signal within a predetermined time period; and

in response to determining that the first device does not sense the audio signal within the predetermined time period, transmitting, by the second device, a timeout indication associated with the verification code to the server.

9. The non-transitory, computer-readable medium of claim 8 , wherein the first device is a device to be authorized by the server, the second device is an authorized device by the server, the server generates the verification code after receiving the login request from the first device, and the second device encodes, based on an encoding rule included in the first message received from the server, the verification code into the audio signal for broadcasting.

10. The non-transitory, computer-readable medium of claim 9 , the operations further comprising:

in response to receiving the login request from the first device, transmitting, by the server and to the first device, a second message instructing the first device to perform audio sensing;

receiving, by the server and from the first device, a second verification code, wherein the second verification code is automatically extracted and decoded by the first device from the audio signal broadcasted by the second device; and

verifying, by the server, the first device based on the verification code and the received second verification code.

11. The non-transitory, computer-readable medium of claim 10 , wherein the second message instructs the first device to enable a microphone of the first device.

12. The non-transitory, computer-readable medium of claim 10 , wherein verifying the first device comprises:

determining, by the server, whether the received second verification code matches the verification code; and

in response to determining that the received second verification code matches the verification code:

verifying, by the server, the first device; and

authorizing, by the server, the application login on the first device.

13. The non-transitory, computer-readable medium of claim 8 , wherein the audio signal further includes a device identifier of the second device.

14. The non-transitory, computer-readable medium of claim 8 , wherein the first message is transmitted by the server to the second device through an authorized channel between the server and the second device, and the audio signal is broadcasted by the second device based on near-field acoustic communication.

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, by a server and from a first device, a login request, wherein the login request includes login information used for an application login;

in response to receiving the login request from the first device, transmitting, by the server and to a second device different from the first device, a first message including a verification code, wherein the first message instructs the second device to broadcast an audio signal including the verification code, and the verification code is used to verify the first device by the server;

determining, by the second device, whether the first device senses the audio signal within a predetermined time period; and

in response to determining that the first device does not sense the audio signal within the predetermined time period, transmitting, by the second device, a timeout indication associated with the verification code to the server.
