What the settings are
Admin → Backend Settings → Global Settings has a Google reCaptcha v3 block with three fields:
Saving stores the two keys and the switch position. A search of the application finds no code that reads them afterwards, and no page or form that asks Google for a token. If you fill them in, nothing changes for visitors.
What protects your forms today
These checks run without any setting:- Contact form. One IP address can send three messages in 10 minutes. After that the visitor sees “You have sent a few messages already. Please try again in a few minutes.” The form also carries a hidden field that people leave empty and many bots fill in, and a message with that field filled in is rejected.
- Registration. On Admin → Backend Settings → Registration Settings you can switch User Registration off, so new people cannot sign up. You can also switch Email Verification on, so a new account must confirm its email address before it is used. See Registration and login.
