CAPTCHAs were meant to keep bots out, but too often, they lock people with disabilities out, too. From image classification to click-based tests, many “human checks” are anything but inclusive. There’s no universal solution, but understanding real user needs is where accessibility truly starts.

The Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) has become ingrained in internet browsing since personal computers gained momentum in the consumer electronics market. For nearly as long as people have been going online, web developers have sought ways to block spam bots.

The CAPTCHA service distinguishes between human and bot activity to keep bots out. Unfortunately, its methods are less than precise. In trying to protect humans, developers have made much of the web inaccessible to people with disabilities.
