reCAPTCHA: protect your forms from spam

Sep 27, 2026 1 min read

reCAPTCHA is a free Google service that tells people from bots and stops spam in your forms. It works invisibly, without visitors having to tick any boxes.

Enabling it

  1. Go to google.com/recaptcha/admin and register your site with reCAPTCHA v3.
  2. Add your domain (and edeck.me if your site is also reachable there).
  3. Copy the site key and the secret key.
  4. Here, set Active to “Yes”, paste both keys and click Update.
  5. Send a test form to check that it arrives.

If forms fail after enabling it, check that the domain registered with Google matches your site’s.
