How do I add the script to my website?

Copy the line from your dashboard (Connect → Install). It looks like this:

<script src="https://kinga.evoltecs.com/security.js" data-site-key="pk_..." defer></script>

Paste it just before the closing </body> tag on every page and publish. On React, Vue or Vite sites put it in index.html. On WordPress use a "header and footer scripts" plugin or your theme's footer.

Your site key starts with pk_ and is safe to be public. It only works on your own domain.
