ALTCHA for Joomla!

Introduction

Captcha, Spam Protection, Access & Security, Site Security, Security Tools

Joomla! plugin to implement ALTCHA (https://altcha.org/), the Open Source, proof-of-work, self-hosted CAPTCHA alternative.

What is ALTCHA

Unlike regular CAPTCHA solutions, it does not require your users to solve puzzles, identify blurry photos, or read distorted text. It uses JavaScript and cryptography to prove that it's running on a real browser, which strongly implies there's a real person on the other end. This method of verification is called Proof-of-Work.

The version of ALTCHA we use in this plugin is self-hosted and Open Source which means that it does not connect to a third party server, you do not have to pay to use it, and does not set third party cookies. It is fully GDPR-compliant, and does not require a cookie banner on your site. Moreover, it's WCAG 2.2 compliant, meaning it meets and surpasses the requirements of accessibility legislation in most jurisdictions.

Please note that this plugin does not support the hosted, paid ALTCHA service. Moreover, it does not support the hosted, paid service's anti-spam solution. This plugin will only ever implement the self-hosted, Open Source ALTCHA variant. Thank you for your understanding.
