Captcha
=======
Presentation
------------
Captcha is a security mechanism aimed to prevent robots to submit forms.
Captchas are available on the following forms:
- Login form: where user enters login and password to authenticate
- Password reset by mail form: where user enters mail to recover a lost
password
- Register form: where user enters information to create a new account
.. attention::
We use the Perl module GD::SecurityImage to generate
images, you need to install it if you enable Captcha feature.
