It’s easy to add reCaptcha to various places on your WordPress site. And it protects the WooCommerce side of your site, helping you avoid SPAM and those nasty automated bots.
For instance, adding it to your guest checkout or registration are just a couple of ways to use it.
reCaptcha for WooCommerce
The reCaptcha for WooCommerce extension does that one thing only and it does it easily.
Once you have installed and activated it, you will find the general settings under WooCommerce > Settings > reCaptcha. This is where you put in your reCaptcha site and secret key. Also, fields for a couple of custom error messages.

Then you will find activation and settings for each of these areas:

- WooCommerce Registration
- WooCommerce Login
- WooCommerce Lost Password
- WooCommerce Guest Checkout
- WordPress Login
- WordPress Registration
- WordPress Lost Password
Captcha Options
Within each of the options, you have the choice to toggle it off or on, add a field title, and adjust the reCaptcha theme and size.

And as an example, I have added it here for guest checkout.

It’s that simple to set it up and start catching those bots. You can check out the reCaptcha for WooCommerce extension here.
