Captcha

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

We use the Perl module Authen::Captcha to generate codes and images, which look like this:

Go in General parameters > Portal > Captcha:

• Activation in login form: set to 1 to display captcha in login form
• Activation in password reset by mail form: set to 1 to display captcha in password reset by mail form
• Activation in register form: set to 1 to display captcha in register form
• Size: length of captcha
