Captcha is used during account creation to prevent spam accounts. At the moment we are bound to using Google’s Re-Captcha because the user management tool we are using, PWM, is using Re-Captcha exclusively. PWM is the best solution we found for registering accounts or resetting password.
We are not very proud of using Re-Captcha. In fact we feel quite awful knowing G*** services are infiltrating ours, and it is on our wish list to replace it with an alternative. But so far we did not have the time nor the man power to dive into the subject and learn how to hack some different captcha into PWM instead. We did however, notify the PWM community and hope someone will come up with a solution soon. And as soon as we have some extra time on our hands, we will try to find a workaround to this problem.
Till then we beg for your understanding and patience.
