Yola Forms: Adding a Captcha
A CAPTCHA is a type of challenge-response test as an attempt to ensure that the response is generated by a person. A common type of CAPTCHA requires the user to type letters or digits from a distorted image that appears on the screen.
The Form widget comes with a built-in CAPTCHA, and it helps ensure that your form can't be submitted unless the CAPTCHA is entered. Should a visitor not enter the CAPTCHA words, the form post will fail.
If your form does not have CAPTCHA enabled, here's how to set this up:
2. A dialog box will open.
3. Scroll down to the bottom of the dialog box and click Add new field.
4. Scroll all the way down on the drop down menu and select Spam Protector (Captcha).
5. Click Save and remember to click Publish to update your site.
