Why You Should Stop Using CAPTCHAs
There are few amongst us who won’t have, at some point or another, filled in a CAPTCHA code. CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart” and they are most commonly used to stop automated submissions of web forms, such as registration or contact forms.
CAPTCHAs are widespread, but are they actually damaging the usability of your website? I would argue that there are better alternatives to CAPTCHAs and that you should break the habit of using them on your sites.
