CAPTCHA systems are tests that protect websites from automated threats by checking whether the visitor is a human or a bot. However, these systems can create barriers for people with visual, auditory, or cognitive impairments, making some CAPTCHAs challenging to navigate.

Despite the possible accessibility issues, the Web Content Accessibility Guidelines (WCAG) permit the use of CAPTCHAs, but only if they add certain accessible features. This ensures that security measures do not exclude users with disabilities.

In this article, you’ll learn all about implementing CAPTCHA systems that are as accessible as possible. However, it’s important to remember that no matter how accessible or transparent your CAPTCHA is, it will never be perfect – valid interactions will still be marked as unwanted and bots will still be able to pierce your site’s defences.

For that reason, we’ll also introduce alternative solutions that offer greater security and inclusivity, adhering to the highest standards of web accessibility to improve the experience for all users.
