We are planning to build an extranet application which will have forms for both internal and external audience. There needs to be a form for external audience in pre-login phase. As a measure of security, we would like to implement capcha. New to Mendix so exploring. Pls. advise for any approach on Mendix either out of the box or custom. Thanks.
Currently there are several versions of captcha widget/modules available on app store and one of them is reCaptcha Module that uses google captcha 2.0. Not sure if this is still compatible with version 8.9.0 but give it a try.
In this forum post Erwin mentioned he is working on Captcha 3.0 and will publish to app store once its ready, so stay tuned.
