Gregwar Captcha

This plugin enables displaying CAPTCHA on login screen, ensuring that only humans can log in. Plugin makes use of Gregwar PHP Captcha library.

Unlike Google ReCaptcha plugin, this one doesn't rely on external web services and can even be used in local networks without Internet access.

Upon downloading and extracting plugin package, rename its main directory from:

plugin-gregwar-captcha-master

to:

gregwar-captcha

Then you'll need to deploy the plugin so that its index file is available at the following location:

data/plugins/gregwar-captcha/index.php

To enable the plugin, add the following to array defined in data/settings/config.php file:

'plugins.gregwar-captcha' => true,
'plugins.gregwar-captcha.options.limit-count' => 0,

limit-count value denotes number of unsuccessful login attempts required for CAPTCHA to be displayed. If it's set to 0, CAPTCHA is always displayed; if set to 3, it will only be displayed upon 3 failed login attempts.
