In what scenarios would implementing a Single Sign-On solution be more appropriate than handling password authentication through direct PHP scripts?

Implementing a Single Sign-On solution would be more appropriate than handling password authentication through direct PHP scripts in scenarios where you have multiple applications or services that require user authentication. Single Sign-On allows users to log in once and access all connected applications without having to enter their credentials multiple times. This not only improves user experience but also enhances security by centralizing authentication processes. 

<?php

// Code for handling user authentication using Single Sign-On solution

// Check if user is already authenticated
if($_SESSION['is_authenticated']){
    // User is already authenticated, proceed with accessing the application
    echo "Welcome back, ".$_SESSION['username']."!";
} else {
    // Redirect user to Single Sign-On login page
    header("Location: sso_login.php");
    exit();
}

?>
