CAPTCHA – Completely Automated Public Turing test to tell Computers and Humans Apart.
Netacea has the option to utilise Google reCAPTCHA v2. This verifies if an interaction is legitimate with the “I am not a robot” checkbox. It is easy for humans to solve, but difficult for bots and other malicious software.
When a visitor requests a path that is protected by Netacea/reCAPTCHA, an "I am not a robot" checkbox is displayed. Depending on the Security Preference, the visitor may also be presented with a picture puzzle to solve.
If the reCAPTCHA challenge is solved, the page will reload and the user will be able to proceed with their journey. If the challenge is not attempted or failed, the user will not be able to progress past this page.
Security Preference Explained
Choosing the Security Preference is entirely down to personal choice and what type of challenge you would like to be shown.
Easiest for users = Most users (but not 100%) will be presented with the "I am not a robot" checkbox only.
Most Secure = Most users (but not 100%) will be presented with the "I am not a robot" checkbox AND be asked to solve a picture puzzle.
The Middle default is somewhere in between.
