Getting Started

Browser Compatibility

We ensure browser compatibility in Chrome, Safari, Firefox and IE >= 11.

Installation

Install Lock into your project using npm:

npm install auth0-lock

From CDN

<!-- Latest patch release (recommended for production) -->
<script src="https://cdn.auth0.com/js/lock/13.0.0/lock.min.js"></script>

Configure Auth0

Create a Single Page Application in the Auth0 Dashboard.

If you're using an existing application, verify that you have configured the following settings in your Single Page Application:

• Click on the "Settings" tab of your application's page.
• Scroll down and click on the "Show Advanced Settings" link.
• Under "Advanced Settings", click on the "OAuth" tab.
• Ensure that "JsonWebToken Signature Algorithm" is set to RS256 and that "OIDC Conformant" is enabled. Next, configure the following URLs for your application under the "Application URIs" section of the "Settings" page:

• Allowed Callback URLs: http://localhost:3000
• Allowed Logout URLs: http://localhost:3000
• Allowed Web Origins: http://localhost:3000

These URLs should reflect the origins that your application is running on. Allowed Callback URLs may also include a path, depending on where you're handling the callback (see below). Take note of the Client ID and Domain values under the "Basic Information" section. You'll need these values in the next step.

Configure the SDK

Create either an Auth0Lock or Auth0LockPasswordless instance, depending on your use case:

Auth0Lock

import { Auth0Lock } from 'auth0-lock';

const lock = new Auth0Lock('{YOUR_AUTH0_CLIENT_ID}', '{YOUR_AUTH0_DOMAIN}');

Auth0LockPasswordless

import { Auth0LockPasswordless } from 'auth0-lock';

const lock = new Auth0LockPasswordless('{YOUR_AUTH0_CLIENT_ID}', '{YOUR_AUTH0_DOMAIN}');

Logging In

Configure a listener for the authenticated event to retrieve an access token and call show to display the Lock widget.

<button id="login">Click to Login</button>

lock.on('authenticated', function (authResult) {
  lock.getUserInfo(authResult.accessToken, function (error, profileResult) {
    if (error) {
      // Handle error
      return;
    }

    accessToken = authResult.accessToken;
    profile = profileResult;

    // Update DOM
  });
});

// Show the widget when the login button is clicked
document.getElementById('login').addEventListener('click', () => {
  lock.show()
});.

For other comprehensive examples and documentation on the configuration options, see the EXAMPLES.md document.
