Introduction: In this article I will explain how we can Integrate Facebook Login authentication to website.

Description:

To integrate Facebook authentication in website firstly we have to create Facebook App Id. For this open the link https://developers.facebook.com/apps/?action=create. If you are already loged in than you will redirect to Create App other you redirect to login page. After login to Facebook a pop up will open as shown in snapshot:

Enter App name and click on Continue button. Here I Enter App name Test. After that captcha window will be open and enter the text as shown in attached snapshot:

Now you will redirect to your App page and see the structure as attached snapshot:

Enter URL of your website in Site URL field (e.g. http://www.example.com) and click on save changes button.

Add a new webform to project. After that add the Facebook Javascript SDK in between body Tag of .aspx page as mention below:

<body>

    <form id="form1" runat="server">

  

    <div id="fb-root"></div>

<script>

    window.fbAsyncInit = function () {

        FB.init({

            appId: '636863302999119', // App ID

            channelUrl: '//' + window.location.hostname + '/channel', // Channel File

            status: true, // check login status

            cookie: true, // enable cookies to allow the server to access the session

            xfbml: true  // parse XFBML

        });

        FB.Event.subscribe('auth.authResponseChange', function (response) {

            // Here we specify what we do with the response anytime this event occurs.

            if (response.status === 'connected') {

                // The response object is returned with a status field that lets the app know the current

                // login status of the person. In this case, we're handling the situation where they

                // have logged in to the app.

                document.getElementById('auth-displayname').innerHTML = me.name;

                testAPI();

            } else if (response.status === 'not_authorized') {

                // In this case, the person is logged into Facebook, but not into the app, so we call

                // FB.login() to prompt them to do so.

                // In real-life usage, you wouldn't want to immediately prompt someone to login

                // like this, for two reasons:

              

                FB.login();

            } else {

                // In this case, the person is not logged into Facebook, so we call the login()

                FB.login();

            }

        });

    };

    // Load the SDK asynchronously

    (function (d) {

        var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];

        if (d.getElementById(id)) { return; }

        js = d.createElement('script'); js.id = id; js.async = true;

        js.src = "//connect.facebook.net/en_US/all.js";

        ref.parentNode.insertBefore(js, ref);

    } (document));

</script>

<!--

  Below we include the Login Button social plugin. This button uses the JavaScript SDK to

  present a graphical Login button that triggers the FB.login() function when clicked.

  Learn more about options for the login button plugin:

  /docs/reference/plugins/login/ -->

<table align="center">

<tr><td>

<div id="auth-status">

<div class="fb-login-button" show-faces="true" autologoutlink="true" scope="email,user_checkins">Login with Facebook</div>

<div id="auth-loggedout">

</div>

</td></tr>

</table>

    </form>

</body>

Run the project an check out the result.
