Easy Captcha is an ideal solution for those who want to try different types of captcha to achieve an optimal site usability and captcha protection ratio. It allows a WordPress site owner to choose which captcha should be used on a particular page.
Currently the plugin supports 3 types of captcha:
<ul>
<li>Hidden captcha, </li>
<li>Simple image captcha,</li>
<li>Google reCaptcha</li>
</ul>
Hidden Captcha is invisible to site visitors and does not assume any specific user actions. It just checks that a visitor behaves like a human. Although it might seem that Hidden Captcha does not fully correspond to the definition of CAPTCHA (found at the end of the FAQ), it still distinguishes a human from a bot based on natural human behavior. Hidden Captcha also allows checking whether a visitor’s browser has JavaScript and Cookies enabled.
Simple Captcha works in a traditional manner: it shows an image and requires a user to enter a captcha code. Simple Captcha stores captcha values on the server side using a custom session approach.
reCaptcha is a reliable and powerful captcha service provided by Google for free. Please visit <a href="http://google.com/recaptcha" rel="nofollow ugc">reCaptcha site</a> for more details
Any type of captcha from above may be added to the following WordPress site places:
<ul>
<li>Comment forms,</li>
<li>Login page,</li>
<li>Registration page,</li>
<li>Password reset page. </li>
</ul>
With Easy Captcha you can easily install different types of captcha on each individual page.
Please read the FAQ and Installation sections for more details.
