1. A vehicle comprising:
a first communication circuit configured to communicate with a smartphone using a first communication scheme;
a second communication circuit configured to communicate, using a second communication scheme, with an accessory; and
a processor operatively connected to the first communication circuit and the second communication circuit,
wherein the processor is configured to:
control the first communication circuit to broadcast, using the first communication scheme, a discovery signal for searching for the smartphone, wherein the discovery signal comprises a signal requesting a connection to the smartphone;
receive a response signal corresponding to the discovery signal through the first communication scheme, the response signal including an identifier from the smartphone;
determine whether to connect the accessory through the second communication scheme based on whether the identifier from the smartphone included in the response signal is identical with an identifier received from the accessory through the second communication scheme;
control the second communication circuit to be connected to the accessory through the second communication scheme based on the determination;
determine a distance between the accessory and the vehicle, based on a signal comprising data which is transmitted by the accessory through the second communication scheme and is used to authenticate the smartphone;
authenticate, based on the data, the smartphone in response to determining that the distance between the accessory and the vehicle is within a first distance; and
perform an operation related to the authentication when the distance between the accessory and the vehicle is within a second distance and the authentication is completed.
