Simple to Implement, Easy to Extend

We provide an out-of-the-box authentication & authorization platform for any application — with the extensibility to fit your needs.

Integrate your application with Auth0. To log in, users are redirected to Auth0's customizable login page. Once the user logs in successfully, Auth0 redirects them back to your app, returning a token with their auth & user information.

Control & Customize — Extend with Code

All applications and scenarios are different. Auth0\'s Rules, Extensions, and Hooks extend the functionality of Auth0\'s base product to adapt it to your company needs and integrate it with other applications and services.

function defaultPictureForNullAvatars(user
1: The user object stores information about the logged in user, returned by the identity provider. It is generated when a user authenticates, before rules run.
, context
2: The context object stores contextual information about the current authentication transaction, such as the user's IP address, application, or location.
, callback
3: A function that will run after your main code is executed.
) {
if (user.picture.indexOf('cdn.auth0.com') > -1) {
    const url = require('url');
4: Rules run in a JavaScript sandbox. The sandbox supports the ECMAScript 6 language and a large number of Node.js (version 8+) modules that you can import.

    const u = url.parse(user.picture, true);
    u.query.d = 'URL_TO_YOUR_DEFAULT_PICTURE_HERE';
    delete u.search;
    user.picture = url.format(u);
   }
callback(null, user, context);
}

Rules and Hooks are JavaScript code snippets that run in Auth0 as part of the authentication pipeline. They empower you to control and customize any stage of the authentication pipeline.

Calling APIs and External Resources

Once your user authenticates, Auth0 will generate an ID Token and an Access Token that will be passed back to your application. The Access Token can then be used to call your API and/or any external resource.
