An introduction to the many types of CAPTCHAs<\/h2>\n

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) does exactly what its unwieldy full name implies. It offers a test designed to tell the difference between humans and bots or other computer programs.<\/p>\n

CAPTCHAs have been used all across the internet for some time. Their most common form has been as a series of distorted letters and\/or numbers:<\/p>\n

\"An<\/p>\n

A human can generally make sense of this image, while bots can get confused by the curved letters. However, there are issues with this type of CAPTCHA. It\u2019s often hard for humans to actually read, and bots are getting much better<\/a> at puzzling these images out.<\/p>\n

So while you still see this type of CAPTCHA sometimes, simpler forms have become more common. Sometimes you’re asked to pick out images that meet certain criteria. In other cases, you have to solve a basic math problem:<\/p>\n

This type of CAPTCHA monitors the movements of your mouse, in order to tell whether or not you\u2019re human. New, research-based CAPTCHAs like this are likely to keep appearing over time.

The pros and cons of using a WordPress CAPTCHA<\/h2>\n

Of course, there are also arguments against using CAPTCHAs<\/a>:<\/p>\n
