         2 . The user terminal apparatus as claimed in  claim 1 , wherein the preset text input mode is a text input mode for generation of a user account. 
     
     
         3 . The user terminal apparatus as claimed in  claim 2 , wherein the controller recognizes a user fingerprint according to a user command for input of ID and PASSWORD in a text input mode for generation of the user account. 
     
     
         4 . The user terminal apparatus as claimed in  claim 1 , wherein the user scanner is provided in a confirmation button area that receives a user command for input of a specific text on the text input UI. 
     
     
         5 . The user terminal apparatus as claimed in  claim 4 , wherein the controller recognizes a user fingerprint by as much as a pressing and manipulating number of times of the confirmation button area and transmits a plurality of pieces of fingerprint information corresponding to the recognized user fingerprint to the electronic apparatus. 
     
     
         6 . The user terminal apparatus as claimed in  claim 1 , wherein the controller activates the fingerprint scanner in response to the electronic apparatus entering the preset text input mode, and deactivates the fingerprint scanner in response to the electronic apparatus getting out of the preset text input mode. 
     
     
         7 . The user terminal apparatus as claimed in  claim 6 , wherein the controller determines whether the electronic apparatus enters the preset text input mode based on a signal received from the electronic apparatus. 
     
     
         8 . An electronic apparatus comprising:
 a display unit configured to display a text input user interface (UI);   a communication unit configured to communicate with a user terminal apparatus and to receive a user command for input of a specific text on the text input UI; and   a controller configured to store information corresponding to a user fingerprint recognized based on the user command as authentication information associated with a preset text input mode in response to the information corresponding to the user fingerprint being received from the user terminal apparatus in the preset text input mode.   
     
     
         9 . The electronic apparatus as claimed in  claim 8 , wherein the information corresponding to the user fingerprint is received together with the user command for input of a specific text on the text input UI. 
     
     
         10 . The electronic apparatus as claimed in  claim 8 , wherein:
 the preset text input mode is a text input mode for generation of a user account; and   the controller stores the information corresponding to the user fingerprint received from the user terminal apparatus as authentication information about the user account generated in the text input mode for generation of the user account.   
     
     
         11 . The electronic apparatus as claimed in  claim 8 , wherein the controller stores the information corresponding to the user fingerprint received from the user terminal apparatus as the authentication information about the user account and then performs authentication based on the stored information in response to an authentication event about the user account occurring. 
     
     
         12 . The electronic apparatus as claimed in  claim 11 , wherein the information corresponding to the user fingerprint is generated based on information recognized through a fingerprint scan sensor included in a preset button area that receives the user command from the user terminal apparatus. 
     
     
         13 . The electronic apparatus as claimed in  claim 11 , wherein the controller transmits a corresponding signal to the user terminal apparatus and controls the fingerprint scan sensor included in the preset button area to be activated in response to the electronic apparatus entering the preset text input mode. 
     
     
         14 . A user terminal apparatus using a password authentication method, the user terminal apparatus comprising:
 an input unit comprising a touch panel;   a fingerprint scanner disposed in one area of the touch panel; and   a controller configured to perform user authentication based on a password input via a touch method through the touch panel and to perform additional authentication based on fingerprint information acquired during password input using the touch method.   
     
     
         15 . The user terminal apparatus as claimed in  claim 14 , wherein the password authentication method comprises at least one of a pattern authentication method and a number authentication method. 
     
     
         16 . The user terminal apparatus as claimed in  claim 15 , further comprising a display unit configured to display a guide graphic user interface (GUI) for guidance of the password input,
 wherein the fingerprint scanner is disposed in an area in which the guide GUI is displayed.   
     
     
         17 . The user terminal apparatus as claimed in  claim 15 , wherein:
 the password authentication method is a pattern authentication method; and   the controller acquires user fingerprint information in at least one of a touch point in which the pattern input is begun, a touch point in which a direction is changed during the pattern input, and a touch point in which the pattern input is terminated.   
     
     
         18 . The user terminal apparatus as claimed in  claim 15 , wherein:
 the password authentication method is a pattern authentication method; and   the controller acquires user fingerprint information based on pattern input for pattern registration in a pattern registration mode for pattern authentication and stores the acquired fingerprint information as reference fingerprint information for fingerprint authentication.   
     
     
         19 . The user terminal apparatus as claimed in  claim 18 , wherein the controller provides a user interface (UI) for guidance of a corresponding fact when the user fingerprint information is not normally acquired in the pattern registration mode.
