To show the hCaptcha you need to modify the registration template. You can find the files in your Keycloak installation under `themes/base/login/`. If you use the user profile preview (you start your Keycloak with the `-Dkeycloak.profile=preview` flag), you need to edit the `register-user-profile.ftl`, else the `register.ftl`. Add the following code beneith the reCaptcha code:
```html
<#if hcaptchaRequired??>
<div class="form-group">
<div class="${properties.kcInputWrapperClass!}">
<div class="h-captcha" data-size="<#if hcaptchaCompact?? && hcaptchaCompact=="true">compact<#else>normal</#if>" data-sitekey="${hcaptchaSiteKey}"></div>
</div>
<#if mosparoRequired??>
<div class="form-group">
<div class="${properties.kcInputWrapperClass!}">
<div id="mosparo-box"></div>
<script type="module">
var m;
window.onload = function(){
m = new mosparo(
'mosparo-box',
'${mosparoHost}',
'${mosparoUuid}',
'${mosparoPublicKey}',
{ loadCssResource: true }
);
};
</script>
</div>
</div>
</#if>
```
