Portal Showcase

Note

You can choose between SimpleCaptcha and ReCaptcha implementations by modifying the value of the captcha.engine.impl property in your portal-ext.properties file.

For more information, see the default values in the "Captcha" section of Liferay Portal's portal.properties file.

portal:captcha

Captcha is a UIInput that renders Liferay Portal's captcha image and a field for editing single-line text. It provides built-in validation in order to make sure that the text value entered by the user matches the value in the captcha image.

General Usage

The value attribute can be bound to a model bean property via EL.
