# Captcha {% hint style="info" %} Availability of the functionality depends on the license and may not be available in all deployments. {% endhint %} The captcha component is a Google widget whose purpose is to allow submission only of data filled out by a human. ![](/files/a6f0af5ad5f72d0af935218459bbde686c56415a) ## Component properties The component can be placed on the form multiple times, and its display can depend on a condition being met.

Figure 1. Captcha component displayed on the form

Providing the value of the captcha placed on the form is always mandatory - verification will be positive when the "I am not a robot" box is checked and, optionally, other actions are performed (imposed by Google).

Figure 2. In the example, the "I am not a robot" box was not checked, which caused a validation error message to be displayed

Component validation occurs after correctly selecting the graphic. The component stores 3 types of states: too long a waiting time after verification - "expired", positive verification - "ok" or negative - "noOk". Interactions on the form may depend on the component state.
