User Management

Easy to use authentication APIs designed to provide a flexible, secure, and fast integration.

Introduction

Integrating User Management features into your app is quick and easy. In this guide, we’ll walk you through adding a hosted authentication flow to your application using AuthKit.

In addition to this guide, there are a variety of example apps available to help with your integration.

Before getting started

To get the most out of this guide, you’ll need:

A WorkOS account

Your WorkOS API Key and Client ID

1. Configure your project

Let’s add the necessary dependencies and configuration in your WorkOS Dashboard.

Architecture

Server and clientClient-side only

Install dependencies

For a client-only approach, use the authkit-react library to integrate AuthKit directly into your React application. Start by installing the library to your project via npm.

Install React SDK

 npm install @workos-inc/authkit-react

Configure a redirect URI

A redirect URI is a callback endpoint that WorkOS will redirect to after a user has authenticated. This endpoint will exchange the authorization code returned by WorkOS for an authenticated User object. We’ll create this endpoint in the next step.

You can set a redirect URI in the Redirects section of the WorkOS Dashboard. While wildcards in your URIs can be used in the staging environment, they and query parameters cannot be used in production.

For the client-only integration, make sure to set the callback URI as the same route where you require auth.

When users sign out of their application, they will be redirected to your app’s homepage which is configured in the same dashboard area.

All login requests must originate at your application for the PKCE code exchange to work properly. In some instances, requests may not begin at your app. For example, some users might bookmark the hosted login page or they might be led directly to the hosted login page when clicking on a password reset link in an email.

In these cases, AuthKit will detect when a login request did not originate at your application and redirect to your application’s login endpoint. This is an endpoint that you define at your application that should call the signIn method, along with the context search parameter that may have been included in the request. See the code examples below in part 2 of this guide for more information.

You can configure the initiate login URL from the Redirects section of the WorkOS dashboard.

Configure CORS

Since your user’s browser will be making calls to the WorkOS API directly, it is necessary to add your domain to the allow list in your WorkOS Settings. This can be configured in the Configure CORS dialog on the Authentication page of the WorkOS dashboard.

While building your integration in the Staging environment you should add your local development URL here. In the example below we’re adding http://localhost:5173 to the list of allowed web origins.

The code examples use your staging API keys when signed in

2. Add AuthKit to your app

Let’s integrate the hosted authentication flow into your app.

Wrap your app with the AuthKit provider

The AuthKitProvider component will handle the redirect from Hosted AuthKit, refresh the session when needed and provide context for hooks used in the components of your app. Initialize it with your client ID, which you can find in the WorkOS dashboard.

/app/root.tsx

JavaScript

 import { AuthKitProvider } from '@workos-inc/authkit-react';

export default function Root() {
  return (
    <AuthKitProvider clientId="client_123456789">
      <App />
    </AuthKitProvider>
  );
}

For security reasons, the client-only integration cannot be nested inside an iframe.

Use the auth hook in your components

The useAuth hook will return user information and loading status. It also provides functions to retrieve the access token and sign in and sign out the user.

/app.jsx

JavaScript

 import * as React from 'react';
import { useAuth } from '@workos-inc/authkit-react';

export default function App() {
  const { isLoading, user, getAccessToken, signIn, signUp, signOut } =
    useAuth();

  // This `/login` endpoint should be registered on the "Redirects" page of the
  // WorkOS Dashboard. In a real app, this code would live in a route instead
  // of in the main <App/> component
  React.useEffect(() => {
    if (window.location.pathname === '/login') {
      const searchParams = new URLSearchParams(window.location.search);
      const context = searchParams.get('context') ?? undefined;

      // Redirects to the signIn page with the required context
      signIn({ context });
    }
  }, [window.location, signIn]);

  // isLoading is true until WorkOS has determined the user's authentication status
  if (isLoading) {
    return <p>... insert cool spinner here ...</p>;
  }

  // If user doesn't exist, then the user is signed out
  if (!user) {
    return (
      <>
        <button
          onClick={() => {
            // Redirects to the signIn page
            signIn();
          }}
        >
          Sign in
        </button>
        <button
          onClick={() => {
            // Redirects to the signUp page
            signUp();
          }}
        >
          Sign up
        </button>
      </>
    );
  }

  // Show the logged in view
  return (
    <>
      <p>Welcome back{user.firstName && `, ${user.firstName}`}</p>
      <p>
        <button
          onClick={async () => {
            // getAccessToken will return an existing (unexpired) access token, or
            // obtain a fresh one if necessary
            const accessToken = await getAccessToken();
            console.log(`Making API request with ${accessToken}`);
          }}
        >
          Make API Request
        </button>
      </p>
      <p>
        <button
          onClick={() => {
            signOut();
          }}
        >
          Sign Out
        </button>
      </p>
    </>
  );
}

Protect routes with custom hooks

If you have routes that you wish to only be accessible to logged in users, you can use a custom React hook.

/hooks/use-user.ts

TypeScript

 import { useAuth } from '@workos-inc/authkit-react';
import { useEffect } from 'react';
import { useLocation } from 'react-router-dom';

type UserOrNull = ReturnType<typeof useAuth>['user'];

// redirects to the sign-in page if the user is not signed in
export const useUser = (): UserOrNull => {
  const { user, isLoading, signIn } = useAuth();
  const location = useLocation();

  useEffect(() => {
    if (!isLoading && !user) {
      // Use 'state' to return the user to the current page after signing in
      signIn({ state: { returnTo: location.pathname } });
    }
  }, [isLoading, user]);

  return user;
};

Then use that hook to protect your mandatory sign in routes.

/app/protected.jsx

JavaScript

 import { useUser } from '../hooks/use-user';

export default function MyProtectedPage() {
  const user = useUser();

  if (!user) {
    // Redirect to sign in page
    return '...';
  }

  return (
    <>
      <p>Welcome back{user.firstName && `, ${user.firstName}`}</p>
    </>
  );
}

If you haven’t configured your app’s homepage in the WorkOS dashboard, users will see an error when logging out.

Validate the authentication flow

Navigate to the authentication endpoint we created and sign up for an account. You can then sign in with the newly created credentials and see the user listed in the Users section of the WorkOS Dashboard.
