Client: Request JWT from my API by calling /verify-access-token endpoint. var pendingCred = error.credential; // The provider account's email address. username = user.UserName; } // common process: Facebook claims update, Login token generation user = await UserManager.FindByNameAsync(username); // Optional: make email address confirmed when user is logged in from Facebook. Please note that I am still heavily researching on all this stuff, so that might not be a perfect answer. auth.signInWithPopup(provider).then(function(result) { // Remember that the user may have signed in with an account that has a different email // address than the first one.

Once I determine which user is logging in, I create my own access token, and that token is used from that point going forward.

Email Sign Up or sign in with Google Facebook REST API for website which uses Facebook for authentication Ask Question up vote 72 down vote favorite 69 We have a website where the only way to login and authenticate yourself with the site is with Facebook (this was not my choice). Customizing the redirect domain for Facebook sign-in On project creation, Firebase will provision a unique subdomain for your project: This will also be used as the redirect mechanism for OAuth sign in. In hindsight, your method might be the best one to take, but there is alot of studying to do to understand OWIN/Katana and all the microsoft blogs just score cheap points describing how to use the templates rather than explaining whats going inside of Katana –Obi Onuorah Jan 22 '14 at 15:53 1 s0nica I am trying this approach using Google OAuth and it looks good and I was able to create a token that can be used by my mobile app. –Peppe L-G Aug 19 '16 at 20:06 2 Do not request accesstoken in Client. However, this means that users may see that domain while signing in to Facebook before redirecting back to the application: Continue to: To customize the URL in the message to show a custom domain: Continue to: Create a CNAME record for your custom domain that points to your project's subdomain on firebaseapp.com: auth.custom.domain.com CNAME my-app-12345.firebaseapp.com Add your custom domain to the list of authorized domains in the Firebase console: auth.custom.domain.com. What about doing it like this: Show a login form with a "Facebook login" button If this login method is chosen, act kinda like the Facebook SDK: open a web page from your authentication server, which will initiate the Facebook login. var credential = error.credential; // .

Only one problem, when login in using the web api, it save the facebook userid on the provider key field in the aspnetuserlogins table and when login in using the website, it saves different user id in the same field. I had tried to post this as a comment instead of an answer, as I do not provide a real solution, but it's too long. }); } else { // User is already signed-in Firebase with the correct user. See photos and updates from friends in News Feed. firebase.auth().signOut().then(function() { // Sign-out successful. Client: Use Facebook JS SDK to log in and get the access token.

On the CLIENT: Use the Facebook API to login and get an OAUTH2 code. That domain would need to be whitelisted for all supported OAuth providers. To complete the sign in to the intended provider, the user has to sign first to the existing provider (Google) and then link to the former AuthCredential (Facebook access token). Before you begin. –user123456 Sep 10 '14 at 9:15 show 10 more comments up vote 15 down vote Followed by great solution from s0nica, I modified some codes in order to integrate with currently implemented ASP.NET MVC template. For example: provider.setCustomParameters({ 'display': 'popup' }); Reserved required OAuth parameters are not allowed and will be ignored. Of course you'd have to use HTTPS in order not to send the (id,token) pair on the wire in clear text. The API uses RESTful protocol and responses are in JSON format. The idea of using an "extension grant" for the Facebook authentication might involve having to register it to do things properly? I'm not quite sure 5a02188284
