What are you bothered by the most when you use digital products? For me, it’s e-mail and phone verification, pincode, setting complex passwords and not remembering them… and I especially find one particular thing obnoxious, and it’s CAPTCHA.

3 things to consider before you implement CAPTCHA

Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a tool very commonly used on web sources to distinguish between humans and automated computer robots, and more than 6 million websites use Google’s reCAPTCHA. It seems like many of us feel impatient when we’re asked this “Are you a robot?” question (surprisingly, the failure rate for CAPTCHAs is 8–29%; we’re on the same boat), but for those people who have disabilities, it is not just annoying. It is such an inaccessible system.

. Double-check whether CAPTCHA is a necessity for your product.

They protect website registration from bot accounts, allow validating identity, prevent spam and help with securing online shopping. And It’s easy to install and free. CAPTCHAs are pretty beneficial. Yet, you should determine if you actually need them. Many websites use CAPTCHAs for not enough good reasons. If you are running a big e-commerce site, CAPTCHAs might be the only solution. If your product, however, is a small company website, I’m sure you’ll be able to find different tools that achieve the same effect. For example, a social log-in can be a smart way to replace CAPTCHAs in some cases, because those bots don’t have their own social media accounts. We have to know CAPTCHAs exclude your potential users with their inaccessibility, as well as harm your sales.

2. Avoid image-based CAPTCHAs as much as possible

Providing text alternatives may make the CAPTCHA less secure and then it would defeat the purpose. For this reason, some CAPTCHAs don’t have text-alts, causing significant problems for users with vision-related disabilities. The same goes for audio alternatives. We need to take time to explore more accessible tools instead of just installing commonly used ones. Google’s reCAPTCHA v2 and v3 (a simple “I’m not a robot” check box) could be good alternatives to traditional ones because it’s very simple, screen-reader-friendly ,and keyboard accessible. They distinguish humans from bots by how you check the box, as opposed to just verifying whether they checked the box or not. (read more about how it works-here)
