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 has more advanced features like passwordless authentication, while firebase-auth is more focused on Firebase-specific features like phone authentication.
Both packages have TypeScript support, with auth0 having more comprehensive type definitions.
Both packages are compatible with modern browsers, including Chrome, Firefox, and Edge.
auth0 has more dependencies (14) compared to firebase-auth (6), which can affect bundle size and performance.
firebase-auth has better performance due to its smaller bundle size and fewer dependencies.
Both packages are compatible with popular frameworks like React, Angular, and Vue.js.
firebase-auth has a more active community due to its connection to the Firebase ecosystem.
Both packages have high-quality documentation, but auth0's documentation is more comprehensive.
Both packages are actively maintained, with regular updates and bug fixes.

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}', });
