Abstract
A server receives a login request from a first device. The login request includes login information used for an application login. In response to receiving the login request from the first device, the server transmits, to a second device different from the first device, a first message including a verification code. The first message instructs the second device to broadcast an audio signal including the verification code. The verification code is used to verify the first device by the server.
