How do I implement authentication and authorization in a React app?

To implement authentication in a React app, you can use libraries like Firebase, Auth0, or create your own backend with JWT.

What is JWT and how does it work for authentication?

JWT, or JSON Web Token, is a compact token format used for securely transmitting information between parties. It consists of three parts: header, payload, and signature.

Can you show me a simple example of using JWT in a React app?

Sure! First, you would create a login form, then send the credentials to your backend. If valid, the backend returns a JWT, which you store in local storage.

How can I protect certain routes in my React app?

You can use React Router's PrivateRoute component to protect routes. Check if the user is authenticated before rendering the component.
