How to add reCAPTCHA to your Form

Needless to say how much important is the safety of your website. The service that is widely known and combines security with ease of use is reCAPTCHA. It is a free service of Google that protects your website from spam and abuse. 

ReCAPTCHA is easy to be used, but it is hard to be managed by automated malicious software. Convert Forms extension includes reCAPTCHA v2 and you can configure it with just a few steps.

Generate reCAPTCHA Keys in Google

Initially, you have to login into your Google account and visit the corresponding site:

Click on the My reCAPTCHA button.

Add reCAPTCHA to Convert Forms

In Joomla administration environment click on Global Configuration -> Convert Forms and choose the tab “Advanced”.
