The Smart Captcha feature in the 123FormBuilder Form Editor

Captcha images are the colorful letters and numbers displayed at the end of your form. They are also referred to as a verification number or verification code. Users have to type those characters in a box, to confirm that they are persons, not robots (robots can not read them). Smart Captcha is the code that shows only if your form is being abused (e.g. multiple submissions from the same IP). Smart Captcha will appear only after the second attempt coming from the same IP address.

You will find the Smart Captcha option in the Security section of your form, under Captcha settings within the form builder. To add captcha to the form, select any of the available Captcha options, as shown below:

  • No Captcha. Tick this option if you want to remove Captcha completely from your online form.
  • Smart Captcha. This option is set by default when creating an online form. The Captcha verification numbers will appear only after the second attempt coming from the same IP address. A different code will be generated each time the form is being accessed.
  • reCAPTCHA. This option generates the reCaptcha from Google, where the form user needs to tick a checkbox. It appears from the start.
