What is CAPTCHA?
A CAPTCHA or a “Completely Automated Public Turing test to tell Computers and Humans Apart,” comes in several shapes, sizes and types. These all work quite well against spam, but some are harder to solve than others, some are more fun than others, and some will benefit you monetarily on your website more than others. There are plenty of examples but the most used ones today include: word solving, audio, branded, 3D and math solutions.
Why do you need captcha?
The reasoning behind why websites implement CAPTCHA codes into their registration processes is because of spam. Those “crazy” letters are a way to check if the person registering or trying to comment is a real live human being as opposed to a computer program attempting to spam the site.
