Auth0's single sign-on (SSO) user authentification for multiple applications with a single set of credentials with React Js

To use Auth0's single sign-on (SSO) feature with a React application, you will need to follow these steps:

  1. First, sign up for an Auth0 account if you don't already have one.

  2. Next, create a new client in the Auth0 dashboard. This represents an application that you want to enable SSO for. Select "Single Page Web Applications" as the type of client.

  3. Follow the steps in the Auth0 documentation to install the auth0-react library and configure it for your client. This library provides higher-level components and functions that make it easier to use Auth0 with React.

  4. In the Auth0 dashboard, navigate to the "Connections" tab and enable any identity providers that you want to allow users to log in with. For example, you might enable Google, Facebook, or LinkedIn.

  5. In your React application, wrap the root component with an Auth0Provider component. This will provide the auth0 object to the rest of your application through the context API.

  6. Use the useAuth0 hook to get the auth0 object and the isAuthenticated and loginWithRedirect functions.

  7. Use the isAuthenticated function to determine whether the user is logged in or not. If they are not logged in, you can use the loginWithRedirect function to initiate the authentication process.

  8. After the user logs in, they will be redirected back to your application with an authorization code. Use the getTokenSilently function to exchange this code for an access token and a refresh token.

  9. Use the access token to authenticate the user and get their profile information. You can also use the getTokenSilently function with the audience and scope options to get a new access token when the current one expires.

That's it! You should now have a working SSO system that allows users to log in to your React application with a single set of credentials.

Well, isAuthenticated method checks if you have set a cookie in your browser, if your applications are not deployed on the same domain, it would not work, but thanks for the guide!
