Add a Google reCAPTCHA field to your forms in WordPress to help protect them from spam. WS Form supports all current reCAPTCHA versions: Version 2 image or audio, Version 2 invisible, and Version 3 action-based invisible reCAPTCHA.
To use reCAPTCHA, register your website with Google and add your site key and secret key. You can enter keys on each field or use global site and secret keys for all reCAPTCHA fields.
Version 3 runs silently and provides a spam score on successful submissions. WS Form stores that score with each submission and shows it on the submissions page as a color-coded indicator from 0% to 100%.
