@firebase/auth

What is @firebase/auth?

The @firebase/auth package is part of the Firebase JavaScript SDK, providing robust authentication functionality for web and mobile applications. It supports various authentication methods, including email and password, third-party providers like Google and Facebook, and more. This package helps in managing user authentication states, securing user data, and integrating with other Firebase services.

What are @firebase/auth's main functionalities?

Email and Password Authentication

Allows users to sign up using their email and password. It also handles user sign-in and management of user sessions.

firebase.auth().createUserWithEmailAndPassword(email, password).then((userCredential) => { var user = userCredential.user; }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });

Social Auth Providers

Supports authentication with different social media providers such as Google, Facebook, Twitter, etc. This example uses Google for authentication.

var provider = new firebase.auth.GoogleAuthProvider(); firebase.auth().signInWithPopup(provider).then((result) => { var token = result.credential.accessToken; var user = result.user; }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });

Phone Number Authentication

Enables sign-in using a phone number with SMS verification. This method sends an SMS to the user's phone number with a verification code.

firebase.auth().signInWithPhoneNumber(phoneNumber, appVerifier).then((confirmationResult) => { var verificationCode = window.prompt('Please enter the verification code that was sent to your mobile device.'); return confirmationResult.confirm(verificationCode); }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });
