Auth0 vs Firebase Authentication: Popular User Login Solutions
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.

Getting Started
Requirements
This library supports the following tooling versions:
- Node.js:
>=18
Installation
Using npm in your project directory run the following command:
npm install auth0
Configure the SDK
Authentication API Client
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.
Management API Client
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}', });
See more examples.
