Get started

This guide will get you started on setting up the Turnstile widget.

If you are currently using a CAPTCHA service, you can copy and paste our script wherever you have deployed the existing script today.

​​ Get a sitekey and secret key

To start using the Turnstile widget, you will need to obtain a sitekey and a secret key. The sitekey and secret key are always associated with one widget and cannot be reused for other widgets.

The sitekey is public and used to invoke the Turnstile widget on your site.

The sitekey and secret key are generated upon the creation of a widget, allowing communication between your site and Cloudflare to verify responses for a solved challenge from Turnstile. Make sure you keep the secret key safe for security reasons.
