keycloak-login-recaptcha

By default Keycloak ( up to 4.4.0) only supports ReCaptcha for Regsitration, not login. so we created a simple module for activating recaptcha for login

How to use

for building you need to run mvn clean install. it will produce a jar target/recaptcha-login.jar. for making it accessible in Keycloak you should copy this jar into keycloaks standalone/deployment/ directory. just it. if you're using it in docker environment you should mount it in /opt/jboss/keycloak/standalone/deployment/recaptcha-login.jar for example in my docker compose file:

...
keycloak:
	image: jboss/keycloak:4.2.1.Final
	.
	.
	.
	volumes:
		- ./realm-config:/opt/jboss/keycloak/realm-config
		- ./my-theme/:/opt/jboss/keycloak/themes/my-theme/
		- ./kc-recaptcha-module/target/recaptcha-login.jar:/opt/jboss/keycloak/standalone/deployments/recaptcha-login.jar
...

and in your theme file you should add this piece of code in your login.ftl template file:

<#if recaptchaRequired??>
<div class="form-group">
	<div class="${properties.kcInputWrapperClass!}">
		<div class="g-recaptcha" data-size="compact" data-sitekey="${recaptchaSiteKey}">			
		</div>
	</div>
</div>
</#if>

you should past it inside your login <form></form> in your login template (login.ftl)

And finally you should enable external origin https://google.com like the way in keycloaks' Recaptcha Documentation mentioned.
