auth0

What is auth0?

The auth0 npm package provides a comprehensive solution for implementing authentication and authorization in web applications. It offers a variety of features including user login, signup, password reset, and social login integrations. Auth0 simplifies the process of securing applications by providing a robust and scalable authentication service.

What are auth0's main functionalities?

User Login

This feature allows users to log in using their username and password. The code sample demonstrates how to use the password grant type to authenticate a user.

const auth0 = require('auth0');
const auth0Client = new auth0.AuthenticationClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID'
});

auth0Client.oauth.passwordGrant({
  username: '[e-mail]',
  password: 'password'
}, function(err, response) {
  if (err) {
    console.error(err);
  } else {
    console.log(response);
  }
});

User Signup

This feature allows new users to sign up for an account. The code sample demonstrates how to create a new user using the ManagementClient.

const auth0 = require('auth0');
const auth0Client = new auth0.ManagementClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET'
});

const data = {
  email: '[e-mail]',
  password: 'password',
  connection: 'Username-Password-Authentication'
};

auth0Client.createUser(data, function(err, user) {
  if (err) {
    console.error(err);
  } else {
    console.log(user);
  }
});

Password Reset

This feature allows users to reset their password. The code sample demonstrates how to request a password reset email.

const auth0 = require('auth0');
const auth0Client = new auth0.AuthenticationClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID'
});

auth0Client.requestChangePasswordEmail({
  email: '[e-mail]',
  connection: 'Username-Password-Authentication'
}, function(err, response) {
  if (err) {
    console.error(err);
  } else {
    console.log(response);
  }
});

Social Login

This feature allows users to log in using their social media accounts. The code sample demonstrates how to initiate a login with Google using the WebAuth client.

const auth0 = require('auth0');
const auth0Client = new auth0.WebAuth({
  domain: 'YOUR_DOMAIN',
  clientID: 'YOUR_CLIENT_ID'
});

auth0Client.authorize({
  connection: 'google-oauth2'
});

Other packages similar to auth0

passport

Passport is a popular authentication middleware for Node.js. It is highly flexible and modular, allowing developers to choose from a wide range of authentication strategies. Unlike Auth0, Passport requires more configuration and setup, but it offers greater control over the authentication process.

firebase

Firebase Authentication provides backend services for easy use of authentication in web and mobile apps. It supports email/password authentication, social login providers, and anonymous login. Firebase is a part of the Google Cloud Platform and offers a more integrated solution for apps already using other Firebase services.

okta

Okta is an enterprise-grade identity management service that provides secure authentication and authorization. It offers similar features to Auth0, including user management, social login, and multi-factor authentication. Okta is known for its robust security features and is often used in enterprise environments.

README

node-auth0

Node.js client library for the Auth0 platform.

Installation

npm install auth0@2.0.0-alpha.5

Usage

Initialize your client class with an API v2 token (you can generate one here).

var token = '{YOUR_API_V2_TOKEN}';
var auth0 = require('auth0')({
  token: token
});

By default the code assumes your account is running in the US West region. If you are running in Europe you can specify:

var token = '{YOUR_API_V2_TOKEN}';
var auth0 = require('auth0')({
  token: token,
  region: 'eu'
});

Alternatively you can just set the domain:

var token = '{YOUR_API_V2_TOKEN}';
var auth0 = require('auth0')({
  token: token,
  domain: 'login.eu.auth0.com'
});

Promises and Callbacks

Be aware that all methods can be used with Promises or callbacks. However, when a callback is provided, no Promise will be returned.

// Using callbacks.
auth0.getUsers(function (err, users) {
  if (err) {
    // Handle error.
  }
  console.log(users);
});


// Using promises.
auth0
  .getUsers()
  .then(function (users) {
    console.log(users);	
  })
  .catch(function (err) {
    // Handle error.
  });

What is Auth0?

Auth0 helps you to:

• Add authentication with multiple authentication sources, either social like Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce, amont others, or enterprise identity systems like Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider.
• Add authentication through more traditional username/password databases.
• Add support for linking different user accounts with the same user.
• Support for generating signed Json Web Tokens to call your APIs and flow the user identity securely.
• Analytics of how, when and where users are logging in.
• Pull data from other sources and add it to the user profile, through JavaScript rules.

Create a free Auth0 Account

1. Go to Auth0 and click Sign Up.
2. Use Google, GitHub or Microsoft Account to login.
