What potential issues can arise when using sessions for password protection in PHP scripts?

One potential issue that can arise when using sessions for password protection in PHP scripts is session hijacking. To prevent session hijacking, you can regenerate the session ID on a successful login to invalidate any previous session data. 

// Start the session
session_start();

// Check if the user is logged in
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in'] === true) {
    // Regenerate the session ID
    session_regenerate_id(true);
}
