Is your website being spammed with orders by some a*****e? Then this is the extension for you.
This is the only extension you will find online that adds a captcha to the checkout page.
It will add a captcha for each payment method of your checkout page and the customer has to complete the captcha text field correctly before the place order button will work.
To activate the captcha for the checkout go to Stores -> Configuration -> Customer -> Customer Configuration -> CAPTCHA. Here you need to select the "Checkout" option for the captcha to be activated.
