Integrating Captcha Into Contact Form

Is it possible to add a captcha (such as Google captcha) to contact forms? 

How would this be done?

The advice here is beyond my level of expertise: 

https://developers.google.com/recaptcha

Sytist 3.9.0 April 28, 20213.9.0 April 28, 2021

• Added reCAPTCHA V2 option to protect forms from spam and malicious bots. (Manual)

You must be on a really old version of Sytist if you don't have that option. 

Ok, I've just updated (5.0.2) and followed the procedure to add the site key and secret key, saving the changes in 'settings - reCAPTCHA'

No change on my contact form?

What have I missed?

See where it says: 

Contact forms (only applies to forms added to a page using the Page Designer (#2 here).

You will need to remove your contact form (edit your contact form page and remove the [FORM] part out of the page text and save) and re-add it using the Page Designer. 

2) Using the page designer to edit the page, select Add Design Element -> Dynamic Content & Forms (you may have to scroll down to get that option) then drag a form element to the page. Then you will select the form to display in the row settings. 

Also uncheck adding to the admin login page until you confirm it is working.

Yes, that's working.

Many thanks for your time.
