I am developing an application where user can register themselves by filling up the registration form or login with their facebook account to use the application. But my problem is- how can I hit the login page of facebook and retrieve the userid, token, session key, username etc when user successfully logins to his facebook account and then redirect him back to my application.
I am really confused searching here and there. I have to just authenticate my user with his facebook account and comeback to my application with userid and all the keys.
please help.
Kind Regards,
Rupesh
Apparently Facebook supports OpenID, so use that. A quick google brings up articles such as http://developers.facebook.com/blog/post/246/

In my Angular2 app I am using Google, Facebook, Twitter and Github authentication. Twitter works fine. The problem is with Facebook and Google.
Facebook:
When I enter my username and password for Facebook login, it says App Not Set Up: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions. whereas while using twitter, the page which should show up on logging in appears.
Google:
When I am not logged in to any of the mail ids the Google authentication works fine. But if I am already logged in to any of my mail ids, then the authentication system takes that mail id itself and logs in to the app. Is there any way to make it such that the system asks which mail id I want to use, even when I am logged in through one id?
Any help would be greatly appreciated. Thanks.
You can force prompt with Google by setting custom parameters. This will give the user the option to switch accounts:
var provider = new firebase.auth.GoogleAuthProvider();
provider.setCustomParameters({prompt: 'select_account'});
firebase.auth().signInWithPopup(provider);
I and a friend are developing an app and would like to use Facebook as a way of users having their own accounts without us having to ask them to store passwords or make users for security and ease of use.
Passport.js has a facebook plugin but it talks about a redirect URL so my question is: is it actually possible to just send information like email address and password to facebook for authorisation and return the users profile without actually redirecting the user to a facebook login page.
I don't see how i could redirect the user to a facebook login while inside my app and also what on earth would i put as the callback URL? Am i just trying to use passport-facebook in the wrong way?
is it actually possible to just send information like email address and password to facebook for authorisation
No. Users are strongly discouraged from giving this information to any 3rd party app, and you are not allowed to ask users for them.
Login with username/email and password happens on Facebook, not in your app. You will get feedback from the login endpoint then that they logged in successfully.
I am using facebook connect to allow users to log-in to my site using facebook. I am using the server side authentication using OAuth in classic ASP, vbscript. I want to know if one of the following is possible:
1) Can I identify if the user has authorized my app without redirecting to the Auth dialog? ie, even before the user clicks the facebook login button to log-in to my site, is there a way I can find out if the user who is currently logged into facebook has authorized my app?
2) How can I get the facebook user Id of the user who is currently logged into facebook? This is outside the facebook authentication process. Does facebook offer some api which I can use to read the fb cookie that is set when a user logs into facebook and get the logged-in users's facebook user id?
Thanks
1) Use FB.getLoginStatus from the JavaScript SDK.
2) If he’s not connected to your app yet, then not at all. Otherwise, see 1)
how can i login my website using facebook credentials that too seamlessly , when i'm already logged in my facebook account in the same session or in another session. For example i'm logged in my fb and when i open website named rottentomatoes.com in the same session or in another session , i can get automatically logged in , without doing anything , as that site use my fb account and automatically get a registered memeber of that site.
i wanna do this things in my website , like things happening with rotten tomatoes.
so far i can use fb account to login in my website using facebook connect .
please help me ....any suggestion will be welcomed.
You need to have a facebook app, then in your site use the facebook js sdk.
You always have different sessions per site, you'll need to make a session for yours, you don't use the facebook session, just the sdk.
When the user loads your page you can use the FB.getLoginStatus to check if the user is logged into facebook and is authenticated with your app, if so then you get the needed user data and can then log the user into your site.
If the user is not logged into facebook, or hasn't authorized your app then you can use the FB.login method to log the user in, when the user comes back from that process you should have the data you need in order to register/log him into your site.
I want to use "LOGIN with Facebook" function for the new website. I have created a page with a Facebook login.
When I am trying to get code from:
https://developers.facebook.com/docs/reference/plugins/login/
It is asking me to create an Application.
So my question is Can I use "Login with facebook" functionality without Facebook Application integration?
No, you can't. Even when you retrieve the code you need for the Login plugin, Facebook instructs you to substitute APP_ID for your own. You'll need an application if you want to retrieve data about that person when they login, for example
email
name
gender
location
etc...
You'll have to authenticate your users with an app_id and app_secret to retrieve an access_token. That access_token is unique per user per application. More info on authentication is here.
Basically, every time you want to query Facebook's databases, with the Graph API or FQL, you do so on behalf of the user. Facebook links these calls to applications so that they will be able to know which application has what permissions and also what they are doing with them.
Click on over to https://developers.facebook.com/apps and after you have verified your Facebook developer account you'll be able to create a new app
