Shortcode Support
Use the [spamoff_bot_protection] shortcode to add Google reCAPTCHA to custom forms, page builders, or theme templates without writing custom code.
Use Cases
- Stop fake WooCommerce orders and card-testing bots — protect Checkout and Guest Checkout with invisible v3 scoring so bots never reach payment.
- Block fake account creation — add Google reCAPTCHA to WooCommerce and WordPress registration and login forms to stop credential stuffing and brute-force attacks.
- Kill comment spam — add Google reCAPTCHA to your WordPress comment form without modifying your theme.
- Protect password resets — stop automated abuse of the Lost Password form.
- Custom forms and page builders — drop the [spamoff_bot_protection] shortcode into any form (contact forms, custom checkout fields, etc.) for coverage outside the built-in list.
- Modern WooCommerce stores on Block Checkout — get real Store API-level protection instead of a plugin that only works on the legacy Classic Checkout shortcode.
How To Use
- Install and activate SpamOff.
- Get a free Site Key and Secret Key at https://www.google.com/recaptcha/admin — choose v2 or v3 depending on which experience you want.
- Go to WooCommerce → Settings → SpamOff → General Settings, paste your Site Key and Secret Key, and pick v2 or v3.
- If using v3, set your Minimum Score (start at 0.5, lower it if real customers get blocked).
- Go to the Advanced Settings tab and toggle on the forms you want protected (Login, Registration, Checkout, Guest Checkout, Lost Password, Comments).
- Optional: go to Customization to set your v2 widget theme/size and edit the failure message.
- Save changes and test by submitting a protected form as a logged-out visitor.
