PURPOSE: A multi device authentication method is provided to facilitate a device-based authentication process as well as a log-in process using an ID and a password, thereby preventing damage due to personal information leakage. CONSTITUTION: A user device is connected to a network system (S100). The network system requests to the user device a device identifier, a temporary password, a user ID, and an identifier of the 4-tuple identification element of a user password (S110). The user device inputs two or more identifiers including a device identifier and a temporary password which are essential identification elements (S120). The network system compares the data and executes an authentication process (S130). If the user device enters the authentication process only with the device identification, the user device inputs the device identifier and the temporary password only.
