I can’t find any info on it, but I tested it locally, and everything seems to work fine.
I followed the README to get the API key (it takes a few seconds).
Overview
This plugin is designed to integrate HCaptcha into the sign-up form of Discourse forums. This plugin aims to enhance security and bot protection by leveraging the privacy-centric features of HCaptcha. The setup process is straightforward and consists of a few easy steps.
Installation
- Create an HCaptcha Account:
- Visit HCaptcha to create an account. After registering, you’ll receive a site key and a secret key.
- Setup Local Testing (Optional):
- If you are testing locally, add a new virtual host entry to your hosts file. Include a line like
127.0.0.1 test.mydomain.com. Make sure the domain is valid, even if you don’t own it, to ensure the HCaptcha script loads properly.
- Configure Plugin Settings:
- Log into your Discourse admin panel.
- Navigate to
Admin>Settings>Plugins>hCaptcha (settings).- In this section, add the site key and secret key you obtained from HCaptcha.
By completing these steps, you will successfully integrate HCaptcha into the sign-up form of your community.
