The present invention relates to an access authentication system using a terminal. The access authentication system using a terminal includes: a visitor terminal receiving an access authentication code from an access control server and displaying the access authentication code to a first input and output means; a resident terminal generating rejection information and transmitting the rejection information to the visitor terminal; an access control server including a visitor information storage unit, an authentication code managing unit, and a code checking unit; and an access control device including a code reader reading the access authentication code, and a door control unit, thereby preventing hacking of the terminal and strengthening security. |
