How we can use Captcha in Sitecore Forms?

Question

How can we show Captcha using Sitecore Forms and validate?

Answer 1

It doesn't exist such a field out of the box.

@Bart Verdonck created a module : https://github.com/bartverdonck/Sitecore-Forms-Extensions which has a control to support google reCaptcha.

You can download it from : https://github.com/bartverdonck/Sitecore-Forms-Extensions/tree/master/downloads

He has a series of blogposts about his module:
