Web Form Builder comes with a built-in security system if you choose to use it: The reCAPTCHA box. You've seen them on the web before, and likely used a few of these genius little boxes.

Included at the end of your form, this box displays two words that the submitter must accurately re-type into the input box in order for the form to be submitted. These words are designed to be impossible for automated programs to identify, stopping them from submitting your form. In other words, if you use a reCAPTCHA box, your form can only be submitted by humans!

To use a reCAPTCHA box, go to the Form Options tab and choose either Automatic (S-Drive only) or Manual from the Captcha drop-down.

Automatic Captcha

All Captcha systems rely on a key of answers to ensure that the image that has been displayed matches up with the answer that is expected. S-Drive has its own set of keys that you can choose to use, but you'll need to be publishing to S-Drive in order to use it. Use this option only if you are publishing to S-Drive or if you use the Automated Form Processing export function.

Style your Captcha

You can style your Captcha by choosing an option from the Theme drop-down that appears.

Manual Captcha

If you're not using S-Drive's automated form processing, or if you just want to use your own keys, you'll need to use the Manual setting. Go to the Form Options tab in Web Form Builder, select Manual from the Captcha drop-down, and two fields will appear that say Public Key and Private Key.

Since you're not using S-Drive's keys, you'll need to provide your own Public and Private keys for the Captcha to work.

Get Your Captcha Keys

Go to the reCAPTCHA website at http://www.recaptcha.org to get your keys. Click USE reCAPTCHA ON YOUR SITE, then click Sign up Now! (You won't actually need to sign up for anything.)

On the next page, enter your domain name in the box at the top of the page, check the box next to Enable this key on all domains (global key), and click Create Key at the bottom of the page.

The following page will contain your public and private keys that you will need to use in Web Form Builder. (The private key has been partially blurred to protect it, since you're supposed to keep this one a secret for security's sake!)

Highlight and copy these two keys one at a time and paste them into the Public Key and Private Key fields.

Your keys are now set up and your Captcha box will work! Please note that these keys will only work on the domain you entered on the reCAPTCHA website. Using this keys for a form on another domain will cause the Captcha because to experience a fatal error.
