<title>Recaptcha Support on Registration</title>
<para>
To safeguard registration against bots, Keycloak has integration with Google Recaptcha. To enable this you
need to first go to <ulink url="https://developers.google.com/recaptcha/">Google Recaptcha</ulink>
and create an API key so that you can get your recaptcha site key and secret. (FYI, localhost works by default
so you don't have to specify a domain).
</para>
<para>Next, go to the Keycloak Admin Console. Go to
Authentication->Flows page. Select the 'registration' flow. Set the 'Recaptcha' requirement to 'Required'. Click
on the 'Configure' button and enter in the Recaptcha site key and secret.
</para>

Finally, you have to change Keycloak's default security headers. In the Admin Console, go to Settings->Security Defenses
of your realm. Add a space and <literal>https://www.google.com</literal> to the values of both the <literal>X-Frame-Options</literal>
and <literal>Content-Security-Policy</literal> headers. i.e.
<programlisting>
frame-src 'self' https://www.google.com
</programlisting>

That's it! You may want to edit register.ftl in your login theme to muck around with the placement and styling
of the recaptcha button. Up to you.
