# CAPTCHA Module for OpenConf

This module adds a CAPTCHA verification to the submission and contact forms so as to ensure they are submitted by a person.

### Requirements and Configuration

If running OpenConf on your own server, sign up for an hCaptcha or a Google reCAPTCHA account and enter your account API keys into this module's settings. Note: PHP must be configured so that allow_url_fopen is enabled.

The OpenConf Hosting Service already has this module pre-configured and no configuration is necessary – simply install and activate the module.
