What are some common pitfalls to avoid when creating a download script with one-time password access in PHP?

One common pitfall to avoid when creating a download script with one-time password access in PHP is not properly validating the one-time password before allowing the download. To solve this issue, ensure that the password is verified before granting access to the download file. 

<?php
// Check if the provided one-time password is valid before allowing download
$valid_password = "secret123";
$provided_password = $_GET['password'];

if ($provided_password != $valid_password) {
    die("Invalid password. Access denied.");
}

// Code to initiate file download goes here
?>
