This utility provides captcha verification in the MODx Manager login. It uses 5 system settings:
captcha.enabled - If set, the captcha function is turned on
captcha.use_mathstring - If set, the image is a simple equation for the user to solve
captcha.words - Selection of words used for the image if captcha.use_mathstring is off
captcha.height - Height of captcha image in pixels
captcha.width - Width of captcha image in pixels
The Captcha components can also be used by other components to create captcha-style verification for front-end forms.
Install via Package Management, then modify the captcha System Settings as desired.
