Are there any specific PHP functions or configurations that can help streamline the authentication process and prevent login windows from popping up multiple times?

To streamline the authentication process and prevent login windows from popping up multiple times, you can use PHP sessions to store the user's authentication status. By checking the session on each page load, you can ensure that the user remains authenticated without the need for multiple login prompts. 

<?php
session_start();

// Check if user is not authenticated, redirect to login page
if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    header('Location: login.php');
    exit();
}

// Your protected page content here
echo 'Welcome, authenticated user!';
?>
