Custom reCaptcha is a plugin that gives you control over the look of Google's reCaptcha. It can replace the standard reCaptcha plugin packaged with Joomla! and adds solutions to make any version of the reCaptcha widget responsive.
- choose version 1, version 2 (no captcha reCaptcha) or the invisible widget,
- use test mode to try reCaptcha without getting domain keys (test keys are used),
- override version 1 templates (choice of 3 templates to start with),
- force challenges in version 2,
- add Google's legal info in place for the invisible flavor of the widget,
- control CSS styles,
- make any version responsive (version 2 adopts a CSS3 transformations trick to fit the widget, challenges included).
