Google reCAPTCHA

reCAPTCHA is a Google service that protects your CAS deployment from spam and abuse. It uses advanced risk analysis techniques to tell humans and bots apart. CAS supports the reCAPTCHA API v2 and v3.

Support is enabled by including the following module in the Overlay:

<dependency>
     <groupId>org.apereo.cas</groupId>
     <artifactId>cas-server-support-captcha</artifactId>
     <version>${cas.version}</version>
</dependency>

To see the relevant list of CAS properties, please review this guide.

Internet Explorer

Remember to disable Internet Explorer’s “Compatibility View” mode. reCAPTCHA may not render correctly when that mode is turned on.
