Both Auth0 and Firebase Auth are popular services that help developers add user login and signup to their websites. They handle tasks like storing user accounts safely, managing passwords, and letting users sign in with services like Google or Facebook. While Auth0 is known for being highly customizable and business-friendly, Firebase Auth is popular for being easier to set up and part of Google's larger Firebase platform.
Both packages provide authentication features, but auth0 supports more authentication providers (e.g., Google, Facebook, GitHub) and has more advanced features like passwordless authentication and multi-factor authentication. Firebase-auth is more focused on Firebase-specific authentication features.
Both packages have TypeScript definitions and are compatible with TypeScript projects.
Both packages are compatible with modern browsers (Chrome, Firefox, Safari, Edge) and support Internet Explorer 11.
Auth0 has no dependencies, while Firebase-auth depends on the Firebase JavaScript SDK.
Both packages are optimized for performance, but Firebase-auth has a slightly larger bundle size.
Both packages are compatible with popular frameworks like React, Angular, and Vue.js.
Both packages have active communities, but Firebase-auth has more contributors and a higher GitHub star count.
Both packages have high-quality documentation, but Firebase-auth's documentation is more comprehensive and includes more code examples.
Both packages are actively maintained, with regular updates and bug fixes.
1import { WebAuth } from '@auth0/web-auth';
2const auth = new WebAuth({
3 domain: 'your-domain.auth0.com',
4 clientId: 'your-client-id',
5 redirectUri: 'http://localhost:3000/callback'
6});
7auth.authorize();
This code creates an instance of the WebAuth class from auth0 and configures it with your domain, client ID, and redirect URI. The authorize() method is then called to initiate the login flow.
1import { getAuth, signInWithPopup, GoogleAuthProvider } from 'firebase/auth';
2const auth = getAuth();
3const provider = new GoogleAuthProvider();
4signInWithPopup(auth, provider).then((result) => {
5 console.log(result.user);
6}).catch((error) => {
7 console.error(error);
8});
This code imports the necessary functions from firebase-auth and creates an instance of the GoogleAuthProvider. The signInWithPopup() function is then called to initiate the login flow with Google authentication.
Both packages are suitable for authentication in JavaScript applications, but the choice depends on your specific needs.
Simple and popular authentication middleware for Node.js. Supports many login methods like username/password, Google, Facebook, and more through plugins called 'strategies'.

This library supports the following tooling versions:
>=18
Using npm in your project directory run the following command:
npm install auth0
This client can be used to access Auth0's Authentication API.
import { AuthenticationClient } from 'auth0'; const auth0 = new AuthenticationClient({ domain: '{YOUR_TENANT_AND REGION}.auth0.com', clientId: '{OPTIONAL_CLIENT_ID}', clientSecret: '{OPTIONAL_CLIENT_SECRET}', });
See more examples.
The Auth0 Management API is meant to be used by back-end servers or trusted parties performing administrative tasks. Generally speaking, anything that can be done through the Auth0 dashboard (and more) can also be done through this API.
Initialize your client class with a client ID, client secret and a domain.
import { ManagementClient } from 'auth0'; var management = new ManagementClient({ domain: '{YOUR_TENANT_AND REGION}.auth0.com', clientId: '{YOUR_CLIENT_ID}', clientSecret: '{YOUR_CLIENT_SECRET}', });
Or, initialize your client class with an API v2 token and a domain.
import { ManagementClient } from 'auth0'; var management = new ManagementClient({ domain: '{YOUR_TENANT_AND REGION}.auth0.com', token: '{YOUR_API_V2_TOKEN}', });
