Hi you have to use Basic User authentication.

I used this Tutorial for the use of Facebook JDK and Codeigniter in my Application: http://www.dannyherran.com/2011/02/facebook-php-sdk-and-codeigniter-for-basic-user-authentication/

But I recommend you to use Javascript SDK for the authentication.

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
  appId      : '[ID]', // App ID
  channelUrl : '[URL]', // Channel File
  status     : true, // check login status
  cookie     : true, // enable cookies to allow the server to access the session
  xfbml      : true  // parse XFBML
});  
var login = false;
 FB.getLoginStatus(function(response) {
          if (response.status === 'connected') {
              console.log('connected');
              login=true;
                // the user is logged in and connected to your
                // app, and response.authResponse supplies
                // the user's ID, a valid access token, a signed
                // request, and the time the access token 
                // and signed request each expire
                var uid = response.authResponse.userID;
                var accessToken = response.authResponse.accessToken;
          }
          else{
              FB.login(function(response) {
               if (response.authResponse) {
                 console.log('Welcome!  Fetching your information.... ');
                 FB.api('/me', function(response) {
                   console.log('Good to see you, ' + response.name + '.');
                   if(login===false)
                   {
                       window.open("[APPLINKONFACEBOOK]", "_top");
                   }
                   //window.location.href=window.location.href;
                   //FB.logout(function(response) {
                     //console.log('Logged out.');
                   //});
                 });
               } else {
                 console.log('User cancelled login or did not fully authorize.');
               }    
             }, {scope: 'email'});
          }});

// Additional initialization code here
};
 (function() {
var e = document.createElement('script');
e.async = true;
e.src = document.location.protocol +
 '//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);  
  }());
  // Load the SDK Asynchronously
 (function(d){
 var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
 js = d.createElement('script'); js.id = id; js.async = true;
 js.src = "//connect.facebook.net/en_US/all.js";
 d.getElementsByTagName('head')[0].appendChild(js);
 }(document));

 </script>
