Hi @marklcm,
We don’t currently extend our reCAPTCHA beyond the WordPress and WooCommerce login and registration pages. You may be able to add an anti-spam plugin or WooCommerce add-on for reCAPTCHA on the checkout in the meantime.
We are looking to expand compatibility to WooCommerce checkout in the future, however, I can’t comment on possible schedules here on the forums. You are welcome to highlight your use-case to?feedback @ wordfence . com?so the development team is aware of the demand.
You may benefit from using the Wordfence plugin and implementing rate limiting, which can throttle or block bots who are accessing pages too quickly. You can find details on the rate-limiting settings in Wordfence here: https://www.wordfence.com/help/firewall/rate-limiting/
Thanks,
Margaret
