Essential for WordPress forms, holy moly the spam.
There is the form protection and overall site protection (little badge often fixed to the bottom left of the browser window)
There is v2 and v3. v2 had the select all traffic lights from the grid below. v3 is behind the scenes.
I would imagine there are slightly different integration steps for forms with contact form 7 versus wpforms or other.
“Site Key” and a “Secret Key” from here. Once implemented you can go back to the admin panel to see some stats on it’s use.
Something Like:
“www.google.com/recaptcha/admin/site/12345”
Contact Form 7: From the WP Dashbaord click on intergation > reCAPTCHA > Setup and you’ll see you need to add a “Site Key” and a “Secret Key.”
WPForms: here Super Simple.
To comply with the reCAPTCHA terms of service, read and implement what was seen during the implementation step. By having the icon in the bottom right users can link to the terms.

May need to reposition badge, in my case blocking my go-top button. Postion is inline which has the highest specificity so you’re going to need to use the !important property.
.grecaptcha-badge {
bottom: 80px !important;
