React Authentication Flow

Build a Login Flow

Create a React login form that authenticates a user and stores a token securely.

Expected output: A working login form that conditionally renders protected content after login.

Hint: Use React state to manage form inputs and simulate token storage in memory.

Implement Protected Routes

Use React Router to create routes that only authenticated users can access.

Expected output: Routes that redirect unauthenticated users to the login page.

Hint: Create a ProtectedRoute component that checks authentication status.

A protected route restricts access to certain parts of a React application, allowing only authenticated users to view those routes.

Tokens can be stored securely using HttpOnly cookies to prevent JavaScript access, or in-memory storage to avoid persistent storage vulnerabilities.

A common method is to check for the presence and validity of an authentication token in the app state or cookies before rendering protected components.
