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
