recaptcha

Hello,

Since this is functionality is not included by default by WooCommerce, you can set up a plugin like:
https://woocommerce.com/products/google-recaptcha-for-woocommerce/

It has a 30-day money-back guarantee. For any pre-sales questions, you can ask them here:
https://woocommerce.com/my-account/create-a-ticket/

You might need to create an account before. Also, feel free to reach out to WooCommerce Customizations Page; they could help achieve the job you need.
https://woocommerce.com/customizations/

Thanks. I hope this provides clarity.
