How can PHP developers balance the trade-off between security and user convenience when implementing login authentication mechanisms that rely on cookies or session IDs?

To balance the trade-off between security and user convenience when implementing login authentication mechanisms that rely on cookies or session IDs, PHP developers can use secure cookies with the 'HttpOnly' and 'Secure' flags to prevent XSS attacks and secure the communication channel with HTTPS. Additionally, developers should regularly regenerate session IDs to prevent session fixation attacks and implement proper input validation and authentication mechanisms to ensure secure user authentication. 

// Set secure cookies with HttpOnly and Secure flags
session_start();
session_regenerate_id(true);
setcookie(session_name(), session_id(), time() + 3600, '/', '', true, true);

// Implement proper input validation and authentication mechanisms
if ($_POST['username'] == 'admin' && $_POST['password'] == 'password') {
    $_SESSION['authenticated'] = true;
    header('Location: dashboard.php');
    exit;
} else {
    echo 'Invalid username or password';
}
