In this lesson, we create an AuthenticationGuard file that uses the Auth0React SDK to protect React routes by requiring login. You need to create the AuthenticationGuard component, pass in a component prop, and use it to protect any React route. ```js import { withAuthenticationRequired } from "@auth0/auth0-react"; import React from "react"; import { PageLoader } from "./page-loader"; export const AuthenticationGuard = ({ component }) => { const Component = withAuthenticationRequired(component); return ; }; ``` Will also demonstrates how to use the AuthenticationGuard component to protect the profile, and admin routes in the application. ```js import { useAuth0 } from "@auth0/auth0-react"; import React from "react"; import { Route, Routes } from "react-router-dom"; import { PageLoader } from "./components/page-loader"; import { AuthenticationGuard } from "./components/authentication-guard"; import { AdminPage } from "./pages/admin-page"; import { CallbackPage } from "./pages/callback-page"; import { HomePage } from "./pages/home-page"; import { NotFoundPage } from "./pages/not-found-page"; import { ProfilePage } from "./pages/profile-page"; import { ProtectedPage } from "./pages/protected-page"; import { PublicPage } from "./pages/public-page"; export const App = () => { return ( } /> } /> } /> } /> } /> } /> } /> ); }; ```
