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
|
||
|
|
||
|
|
||

.. important::
|
||
|
|
||
|
We use the Perl module GD::SecurityImage to generate
|
||
|
images, you need to install it if you enable Captcha feature.
