<h3>External Services</h3>
This plugin uses Google reCAPTCHA v2 to help protect comment forms from automated spam.
When reCAPTCHA is enabled, the plugin loads the Google reCAPTCHA script from: 
https://www.google.com/recaptcha/api.js
When a comment form is submitted, the plugin sends the following data to Google for verification: 
• The reCAPTCHA response token 
• The user’s IP address 
• Your site’s secret key
This verification request is sent to: 
https://www.google.com/recaptcha/api/siteverify

Adds a Google No Captcha ReCaptcha checkbox to your WordPress and Woocommerce login, forgot password, and user registration pages. Denies access to automated scripts while making it easy on humans to log in by checking a box. As Google says, it is “Tough on bots, easy on humans.”

Login No Captcha reCAPTCHA

Great plugin but really needs wildcard support for "Whitelist IP" setting. Many ISPs change IP addresses constantly, so it's a pain to have to always go in and manually add another IP address to the list. I posted a support topic asking for wildcard support about 10 months ago, but zero replies from the plugin developer.

Wildcard support would change my rating to 5 stars easy.

Otherwise I'll eventually fork this plugin and add the wildcard myself (it's trivial to do).

Thanks to the developers for this great plugin.
