Authenticate Using Facebook Login with JavaScript

You can let your users authenticate with Firebase using their Facebook accounts by integrating Facebook Login into your app. You can integrate Facebook Login either by using the Firebase SDK to carry out the sign-in flow, or by carrying out the Facebook Login flow manually and passing the resulting access token to Firebase.

Before you begin

Add Firebase to your JavaScript project. On the Facebook for Developers site, get the App ID and an App Secret for your app. Enable Facebook Login: In the Firebase console, open the Auth section. On the Sign in method tab, enable the Facebook sign-in method and specify the App ID and App Secret you got from Facebook. Then, make sure your OAuth redirect URI (e.g. my-app-12345.firebaseapp.com/__/auth/handler ) is listed as one of your OAuth redirect URIs in your Facebook app’s settings page on the Facebook for Developers site in the Product Settings > Facebook Login config.

Handle the sign-in flow with the Firebase SDK

If you are building a web app, the easiest way to authenticate your users with Firebase using their Facebook accounts is to handle the sign-in flow with the Firebase JavaScript SDK. (If you want to authenticate a user in Node.js or other non-browser environment, you must handle the sign-in flow manually.)

To handle the sign-in flow with the Firebase JavaScript SDK, follow these steps:

Create an instance of the Facebook provider object: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { FacebookAuthProvider } from “firebase/auth”; const provider = new FacebookAuthProvider(); auth_facebook_provider_create.js Web version 8 var provider = new firebase.auth.FacebookAuthProvider(); facebook.js Optional: Specify additional OAuth 2.0 scopes that you want to request from the authentication provider. To add a scope, call addScope . For example: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. provider.addScope(‘user_birthday’); auth_facebook_provider_scopes.js Web version 8 provider.addScope(‘user_birthday’); facebook.js authentication provider documentation. Optional: To localize the provider’s OAuth flow to the user’s preferred language without explicitly passing the relevant custom OAuth parameters, update the language code on the Auth instance before starting the OAuth flow. For example: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth } from “firebase/auth”; const auth = getAuth(); auth.languageCode = ‘it’; // To apply the default browser preference instead of explicitly setting it. // firebase.auth().useDeviceLanguage(); auth_set_language_code.js Web version 8 firebase.auth().languageCode = ‘it’; // To apply the default browser preference instead of explicitly setting it. // firebase.auth().useDeviceLanguage(); index.js Optional: Specify additional custom OAuth provider parameters that you want to send with the OAuth request. To add a custom parameter, call setCustomParameters on the initialized provider with an object containing the key as specified by the OAuth provider documentation and the corresponding value. For example: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. provider.setCustomParameters({ ‘display’: ‘popup’ }); auth_facebook_provider_params.js Web version 8 provider.setCustomParameters({ ‘display’: ‘popup’ }); facebook.js authentication provider reference for more details. Authenticate with Firebase using the Facebook provider object. You can prompt your users to sign in with their Facebook accounts either by opening a pop-up window or by redirecting to the sign-in page. The redirect method is preferred on mobile devices. To sign in with a pop-up window, call signInWithPopup : Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth, signInWithPopup, FacebookAuthProvider } from “firebase/auth”; const auth = getAuth(); signInWithPopup(auth, provider) .then((result) => { // The signed-in user info. const user = result.user; // This gives you a Facebook Access Token. You can use it to access the Facebook API. const credential = FacebookAuthProvider.credentialFromResult(result); const accessToken = credential.accessToken; // … }) .catch((error) => { // Handle Errors here. const errorCode = error.code; const errorMessage = error.message; // The email of the user’s account used. const email = error.customData.email; // The AuthCredential type that was used. const credential = FacebookAuthProvider.credentialFromError(error); // … }); auth_facebook_signin_popup.js Web version 8 firebase .auth() .signInWithPopup(provider) .then((result) => { /** @type {firebase.auth.OAuthCredential} */ var credential = result.credential; // The signed-in user info. var user = result.user; // This gives you a Facebook Access Token. You can use it to access the Facebook API. var accessToken = credential.accessToken; // … }) .catch((error) => { // Handle Errors here. var errorCode = error.code; var errorMessage = error.message; // The email of the user’s account used. var email = error.email; // The firebase.auth.AuthCredential type that was used. var credential = error.credential; // … }); facebook.js This is also where you can catch and handle errors. For a list of error codes have a look at the Auth Reference Docs.

: To sign in by redirecting to the sign-in page, call signInWithRedirect : Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth, signInWithRedirect } from “firebase/auth”; const auth = getAuth(); signInWithRedirect(auth, provider); auth_signin_redirect.js Web version 8 firebase.auth().signInWithRedirect(provider); index.js getRedirectResult when your page loads: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth, getRedirectResult, FacebookAuthProvider } from “firebase/auth”; const auth = getAuth(); getRedirectResult(auth) .then((result) => { // This gives you a Facebook Access Token. You can use it to access the Facebook API. const credential = FacebookAuthProvider.credentialFromResult(result); const token = credential.accessToken; const user = result.user; }).catch((error) => { // Handle Errors here. const errorCode = error.code; const errorMessage = error.message; // The email of the user’s account used. const email = error.customData.email; // AuthCredential type that was used. const credential = FacebookAuthProvider.credentialFromError(error); // … }); auth_facebook_signin_redirect_result.js Web version 8 firebase.auth() .getRedirectResult() .then((result) => { if (result.credential) { /** @type {firebase.auth.OAuthCredential} */ var credential = result.credential; // This gives you a Facebook Access Token. You can use it to access the Facebook API. var token = credential.accessToken; // … } // The signed-in user info. var user = result.user; }).catch((error) => { // Handle Errors here. var errorCode = error.code; var errorMessage = error.message; // The email of the user’s account used. var email = error.email; // The firebase.auth.AuthCredential type that was used. var credential = error.credential; // … }); facebook.js Auth Reference Docs.

Note: http://localhost origin, you need to ensure that development mode is turned on for this Facebook App. In addition, sign-in will only be allowed with Facebook test accounts. Facebook enforces HTTPS and does not allow login with insecure hosts. When using Facebook in development mode with anorigin, you need to ensure that development mode is turned on for this Facebook App. In addition, sign-in will only be allowed with Facebook test accounts.

Handling account-exists-with-different-credential Errors If you enabled the One account per email address setting in the Firebase console, when a user tries to sign in a to a provider (such as Facebook) with an email that already exists for another Firebase user’s provider (such as Google), the error auth/account-exists-with-different-credential is thrown along with an AuthCredential object (Facebook access token). 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). If you use signInWithPopup , you can handle auth/account-exists-with-different-credential errors with code like the following example: // Step 1. // User tries to sign in to Facebook. auth.signInWithPopup(new firebase.auth.FacebookAuthProvider()).catch(function(error) { // An error happened. if (error.code === ‘auth/account-exists-with-different-credential’) { // Step 2. // User’s email already exists. // The pending Facebook credential. var pendingCred = error.credential; // The provider account’s email address. var email = error.email; // Get sign-in methods for this email. auth.fetchSignInMethodsForEmail(email).then(function(methods) { // Step 3. // If the user has several sign-in methods, // the first method in the list will be the “recommended” method to use. if (methods[0] === ‘password’) { // Asks the user their password. // In real scenario, you should handle this asynchronously. var password = promptUserForPassword(); // TODO: implement promptUserForPassword. auth.signInWithEmailAndPassword(email, password).then(function(result) { // Step 4a. return result.user.linkWithCredential(pendingCred); }).then(function() { // Facebook account successfully linked to the existing Firebase user. goToApp(); }); return; } // All the other cases are external providers. // Construct provider object for that provider. // TODO: implement getProviderForProviderId. var provider = getProviderForProviderId(methods[0]); // At this point, you should let the user know that they already have an account // but with a different provider, and let them validate the fact they want to // sign in with this provider. // Sign in to provider. 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. 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. This can happen as Firebase doesn’t control the provider’s // sign in flow and the user is free to login using whichever account they own. // Step 4b. // Link to Facebook credential. // As we have access to the pending credential, we can directly call the link method. result.user.linkAndRetrieveDataWithCredential(pendingCred).then(function(usercred) { // Facebook account successfully linked to the existing Firebase user. goToApp(); }); }); }); } }); Redirect mode This error is handled in a similar way in the redirect mode, with the difference that the pending credential has to be cached between page redirects (for example, using session storage).

Advanced: Handle the sign-in flow manually You can also authenticate with Firebase using a Facebook account by handling the sign-in flow with the Facebook Login JavaScript SDK: Integrate Facebook Login into your app by following the developer docs. Be sure to configure Facebook Login with your Facebook app ID: We also setup a listener on the Facebook auth state: FB.Event.subscribe(‘auth.authResponseChange’, checkLoginState); After you integrate Facebook Login, add a Facebook Login button on your web pages: In the Facebook auth state callback, exchange the auth token from Facebook’s auth response for a Firebase credential and sign-in Firebase: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth, onAuthStateChanged, signInWithCredential, signOut, FacebookAuthProvider } from “firebase/auth”; const auth = getAuth(); function checkLoginState(response) { if (response.authResponse) { // User is signed-in Facebook. const unsubscribe = onAuthStateChanged(auth, (firebaseUser) => { unsubscribe(); // Check if we are already signed-in Firebase with the correct user. if (!isUserEqual(response.authResponse, firebaseUser)) { // Build Firebase credential with the Facebook auth token. const credential = FacebookAuthProvider.credential( response.authResponse.accessToken); // Sign in with the credential from the Facebook user. signInWithCredential(auth, credential) .catch((error) => { // Handle Errors here. const errorCode = error.code; const errorMessage = error.message; // The email of the user’s account used. const email = error.customData.email; // The AuthCredential type that was used. const credential = FacebookAuthProvider.credentialFromError(error); // … }); } else { // User is already signed-in Firebase with the correct user. } }); } else { // User is signed-out of Facebook. signOut(auth); } } auth_facebook_callback.js Web version 8 function checkLoginState(response) { if (response.authResponse) { // User is signed-in Facebook. var unsubscribe = firebase.auth().onAuthStateChanged((firebaseUser) => { unsubscribe(); // Check if we are already signed-in Firebase with the correct user. if (!isUserEqual(response.authResponse, firebaseUser)) { // Build Firebase credential with the Facebook auth token. var credential = firebase.auth.FacebookAuthProvider.credential( response.authResponse.accessToken); // Sign in with the credential from the Facebook user. firebase.auth().signInWithCredential(credential) .catch((error) => { // Handle Errors here. var errorCode = error.code; var errorMessage = error.message; // The email of the user’s account used. var email = error.email; // The firebase.auth.AuthCredential type that was used. var credential = error.credential; // … }); } else { // User is already signed-in Firebase with the correct user. } }); } else { // User is signed-out of Facebook. firebase.auth().signOut(); } } facebook.js Auth Reference Docs. Also you should check that the Facebook user is not already signed-in Firebase to avoid un-needed re-auth: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { FacebookAuthProvider } from “firebase/auth”; function isUserEqual(facebookAuthResponse, firebaseUser) { if (firebaseUser) { const providerData = firebaseUser.providerData; for (let i = 0; i < providerData.length; i++) { if (providerData[i].providerId === FacebookAuthProvider.PROVIDER_ID && providerData[i].uid === facebookAuthResponse.userID) { // We don't need to re-auth the Firebase connection. return true; } } } return false; } auth_facebook_checksameuser.js Web version 8 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.PROVIDER_ID && providerData[i].uid === facebookAuthResponse.userID) { // We don't need to re-auth the Firebase connection. return true; } } } return false; } facebook.js Advanced: Authenticate with Firebase in Node.js To authenticate with Firebase in a Node.js application: Sign in the user with their Facebook Account and get the user's Facebook access token. For example, sign in the user in a browser as described in the Handle the sign-in flow manually section, but send the access token to your Node.js application instead of using it in the client app. After you get the user's Facebook access token, use it to build a Credential object and then sign in the user with the credential: Web version 9 Learn more about the tree-shakeable Web v9 modular SDK and upgrade from version 8. import { getAuth, signInWithCredential, FacebookAuthProvider } from "firebase/auth"; // Sign in with the credential from the Facebook user. const auth = getAuth(); signInWithCredential(auth, credential) .then((result) => { // Signed in const credential = FacebookAuthProvider.credentialFromResult(result); }) .catch((error) => { // Handle Errors here. const errorCode = error.code; const errorMessage = error.message; // The email of the user’s account used. const email = error.customData.email; // The AuthCredential type that was used. const credential = FacebookAuthProvider.credentialFromError(error); // … }); auth_facebook_signin_credential.js Web version 8 // Sign in with the credential from the Facebook user. firebase.auth().signInWithCredential(credential) .then((result) => { // Signed in var credential = result.credential; // … }) .catch((error) => { // Handle Errors here. var errorCode = error.code; var errorMessage = error.message; // The email of the user’s account used. var email = error.email; // The firebase.auth.AuthCredential type that was used. var credential = error.credential; // … }); facebook.js

Authenticate with Firebase in a Chrome extension

If you are building a Chrome extension app, you must add your Chrome extension ID:

Open your project in the Firebase console. In the Authentication section, open the Sign-in method page. Add a URI like the following to the list of Authorized Domains: chrome-extension:// CHROME_EXTENSION_ID

Only popup operations ( signInWithPopup , linkWithPopup , and reauthenticateWithPopup ) are available to Chrome extensions, as Chrome extensions cannot use HTTP redirects. You should call these methods from a background page script rather than a browser action popup, as the authentication popup will cancel the browser action popup. The popup methods may only be used in extensions using Manifest V2. The newer Manifest V3 only allows background scripts in the form of service workers, which cannot perform the popup operations at all.

In your Chrome extension’s manifest file make sure that you add the https://apis.google.com URL to the content_security_policy allowlist.

Customizing the redirect domain for Facebook sign-in On project creation, Firebase will provision a unique subdomain for your project: https://my-app-12345.firebaseapp.com . This will also be used as the redirect mechanism for OAuth sign in. That domain would need to be allowed for all supported OAuth providers. However, this means that users may see that domain while signing in to Facebook before redirecting back to the application: Continue to: https://my-app-12345.firebaseapp.com. To avoid displaying your subdomain, you can set up a custom domain with Firebase Hosting: Follow steps 1 through 3 in Set up your domain for Hosting. When you verify your domain ownership, Hosting provisions an SSL certificate for your custom domain. Add your custom domain to the list of authorized domains in the Firebase console: auth.custom.domain.com . In the Facebook developer console or OAuth setup page, whitelist the URL of the redirect page, which will be accessible on your custom domain: https://auth.custom.domain.com/__/auth/handler . When you initialize the JavaScript library, specify your custom domain with the authDomain field: var config = { apiKey: ‘…’, // Changed from ‘my-app-12345.firebaseapp.com’. authDomain: ‘auth.custom.domain.com’, databaseURL: ‘https://my-app-12345.firebaseio.com’, projectId: ‘my-app-12345’, storageBucket: ‘my-app-12345.appspot.com’, messagingSenderId: ‘1234567890’ }; firebase.initializeApp(config);

Next steps

After a user signs in for the first time, a new user account is created and linked to the credentials—that is, the user name and password, phone number, or auth provider information—the user signed in with. This new account is stored as part of your Firebase project, and can be used to identify a user across every app in your project, regardless of how the user signs in.

In your apps, the recommended way to know the auth status of your user is to set an observer on the Auth object. You can then get the user’s basic profile information from the User object. See Manage Users.

In your Firebase Realtime Database and Cloud Storage Security Rules, you can get the signed-in user’s unique user ID from the auth variable, and use it to control what data a user can access.

You can allow users to sign in to your app using multiple authentication providers by linking auth provider credentials to an existing user account.

To sign out a user, call signOut :
