<p>The present invention relates to a TV application login system which uses a short message service in order to log in a TV application by connecting a mobile terminal such as a smartphone with a TV such as a smart TV in which the application is installed. The present invention includes: a smart TV which generates a login executing window according to a login request about an installed application and requires authentication for a login by transmitting the phone number of a user terminal which is inputted through the login executing window to a service server; the service server which receives the phone number and TV identification information from the smart TV, generates a first authentication key by using the TV identification information, and transmits the generated first authentication key to the user terminal which corresponds to the received phone number by including the generated first authentication key in a short message; and the user terminal which detects the first authentication key which is included in the short message which is received from the service server in the installed application, generates a second authentication key by calculating the detected first authentication key and terminal identification information in a preset way, and transmits the generated second authentication key to the service server. The service server transmits a temporary password to the user terminal by issuing the temporary password from the second authentication key and performs login authentication by comparing the temporary password which is transmitted by being inputted in the smart TV with the issued temporary password.
