What alternative authentication methods can be considered if HTTP-Authentifizierung does not meet the client's requirements?

If HTTP-Authentication does not meet the client's requirements, alternative authentication methods such as token-based authentication, OAuth, or JWT (JSON Web Tokens) can be considered. These methods provide more flexibility and security for authentication processes. 

// Implementing token-based authentication
$token = generateToken(); // Function to generate a unique token

// Store the token in a database or session for future authentication checks
$_SESSION['auth_token'] = $token;

// Verify the token during subsequent requests
if(isset($_SESSION['auth_token']) && $_SESSION['auth_token'] === $token) {
    // User is authenticated
} else {
    // User is not authenticated
}
