For example: provider.setCustomParameters({ 'display': 'popup' }); Reserved required OAuth parameters are not allowed and will be ignored. In the Facebook developer console or OAuth setup page, whitelist the URL of the redirect page, which will be accessible on your custom domain: When you initialize the JavaScript library, specify your custom domain with the authDomain field: var config = { apiKey: '.', // Changed from 'my-app-12345.firebaseapp.com'. var credential = error.credential; // . Before you begin. // The pending Facebook credential. 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. For example: firebase.auth().languageCode = 'frFR'; // To apply the default browser preference instead of explicitly setting it. firebase.auth().signInWithCredential(credential).catch(function(error) { // Handle Errors here. // TODO: implement getProviderForProviderId. You can use it to access the Facebook API. This is also where you can catch and handle errors. if (!isUserEqual(event.authResponse, firebaseUser)) { // Build Firebase credential with the Facebook auth token.

See the authentication provider reference for more details. 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). Also you should check that the Facebook user is not already signed-in Firebase to avoid un-needed re-auth: function isUserEqual(facebookAuthResponse, firebaseUser) { if (firebaseUser) { var providerData = firebaseUser.providerData; for (var i = 0; i < providerData.length; i++) { if (providerData[i].providerId === firebase.auth.FacebookAuthProvider.PROVIDERID && providerData[i].uid === facebookAuthResponse.userID) { // We don't need to re-auth the Firebase connection. ProductsFacebook LoginSharing on FacebookGamesFacebook App Ads. Handle the sign-in flow with the Firebase SDK. You should call these methods from a background script rather than a browser action popup, as the authentication popup will cancel the browser action popup. Note: browsers usually block popup triggered asynchronously, // so in real scenario you should ask the user to click on a "continue" button // that will trigger the signInWithPopup. On the Sign in method tab, enable the Facebook sign-in method and specify the App ID and App Secret you got from Facebook. var credential = error.credential; // . The redirect method is preferred on mobile devices. auth.signInWithEmailAndPassword(email, password).then(function(user) { // Step 4a.
