4) You can enable
CAPTCHAs ("
Completely
Automated
Public
Turing test to tell
Computers and
Humans
Apart") for your ConfTool Pro installation both for new user registrations and the login process (image 5). Please note that usually CAPTCHAs are not required because ConfTool Pro already uses several “invisible” mechanisms to avoid the automatic creation of user accounts. There is no considerable benefit in creating fake user accounts and the system always blocks brute force login attacks.
Two different types of CAPTCHAs are available:
- SecurImage is a classic CAPTCHA that requires a sequence of a few letters to be entered into a text field. This mechanism is provided by ConfTool GmbH and runs on our servers only.
- Google reCAPTCHA V2 requires the user to tick a checkbox or to select a couple of images. This service is considered very secure, but relies on the services of Google. Please note that some people (for example, people living in China) have limited access to Google and this service.
Both types are available for the
login page. If enabled, the user has to complete the CAPTCHA to log in to the system (see images 6 and 7). Please note that after 10 unsuccessful login attempts users and their IP will be blocked for 10 minutes.
If CAPTCHA is enabled for the user registration process, each user has to enter letters correctly ("SecurImage", image 8 ) or tick the checkbox / select the right images ("Google reCAPTCHA V2", see image 9) to create a new user account.
