# Slider Captcha

Essential · [Official website](https://github.com/ArgoZhang/SliderCaptcha)

Slider Captcha is an open source JavaScript component, published on GitHub by ArgoZhang, that asks users to drag a puzzle piece into place to prove they are human. Sites add it to login or registration forms to limit automated submissions. It runs in the site's own code, without relying on an external verification service.
