Lightweight WooCommerce checkout protection for non-production WordPress environments.

What it does

This plugin blocks access to the WooCommerce checkout page on non-production domains until a visitor enters a shared password. It is designed for cloned, staging, and development environments where checkout should stay hidden from normal visitors.

The plugin intentionally fails open on production. If the current host matches a configured production domain, checkout is not protected.

Features

  • Protects the WooCommerce checkout page with a password gate
  • Automatically bypasses protection on configured production domains
  • Automatically bypasses protection for logged-in administrators
  • Skips WooCommerce order-received and order-pay endpoints
  • Uses a WordPress password hash instead of storing a plaintext password
  • Uses a nonce on form submission and hardened cookie flags

Requirements

  • WordPress
  • WooCommerce

Configuration

Edit these constants in checkout-password-protection.php:

  • CPP_PASSWORD_HASH — a wp_hash_password() hash for the checkout password
  • CPP_PRODUCTION_DOMAINS — comma-separated production domains that should never be protected

Example hash generation:

echo wp_hash_password( 'your-chosen-password' );

Replace the placeholder value in CPP_PASSWORD_HASH with the generated hash before using the plugin.

Behavior summary

Checkout protection is skipped when:

  1. The current request is not for checkout
  2. The request is for order-received or order-pay
  3. The current host matches a configured production domain
  4. The current user can manage_options

Otherwise, visitors must enter the configured password to continue to checkout.

Emergency disable

  • Deactivate the plugin in WordPress admin
  • Run wp plugin deactivate checkout-password-protection
  • Rename the plugin folder over SFTP/SSH
