The authentication system in the wireless LAN environment includes a first wireless LAN access point for providing a wireless LAN service to a terminal device accessing the first wireless LAN access point; the terminal device for transmitting an authentication request to a second wireless LAN access point when the terminal device moves to access the second wireless LAN access point while receiving the wireless LAN service through an access to the first wireless LAN access point; and the second wireless LAN access point for identifying the first wireless LAN access point based on identification information contained in the authentication request transmitted from the terminal device which has moved to access the second wireless LAN access point, acquiring authentication information on the terminal device from the identified first wireless LAN access point, and performing an authentication for the terminal device based on the acquired authentication information.
