Do you want a captcha plugin to stop spam bots on your WordPress site?
Captcha is easy to add to your website and helps keep bots out. They won’t be able to submit spam content, spam comments, or fraudulent form entries on your WordPress site. So you reduce your admin work and keep your comments and form submissions clean.
In this guide, we review the best WordPress captcha plugins that make it easy to implement captcha on your site.
What is Captcha for WordPress?
Captcha is a way to stop spam and make your WordPress website more secure. It stands for Completely Automated Public Turing test to tell Computers and Humans Apart.
It is typically used in any areas where users can submit an input such as WordPress login forms, registration forms, comment sections, and contact forms.
The captcha challenge often involves tasks that are easy for humans to complete but difficult for automated scripts to solve. This could be typing distorted characters, selecting images, or solving simple puzzles.
Aside from stopping spam, the main purposes of captcha include:
- Enhanced Security: Adds a layer of protection and enhances the overall security of your website, protecting it from unwanted automated activities.
- User Authentication: Can be used in login forms to ensure that only legitimate users with human-like interactions gain access to restricted areas of the website.
- Form Protection: Safeguards various forms on your site like password reset, checkout, and contact forms, ensuring that submissions are made by real users rather than malicious bots.
When choosing a WordPress captcha plugin, you want to pick one that’s easy to set up and use. It ideally should have a set-and-forget configuration where you set it up once and it runs on its own.
You also want to be sure the pricing fits your budget. There are also plenty of free options out there.
Now let’s check out the best plugins to add Captcha to your site.
Best WordPress Captcha Plugins
WPForms is the best WordPress form builder and is also the best way to add captcha features to your site. It has over 5+ million active installations making it the most popular among contact form plugins.
First, you can create all sorts of forms for your site. This includes contact, login, registration, lost password forms, or even surveys and polls. All of them can be created effortlessly from your WordPress dashboard.
There’s a drag and drop visual builder so you can customize the form fields, submit button, and add/edit elements as needed.
Every form you generate with WPForms includes automatic spam protection. There’s a built-in anti-spam honeypot feature. This creates a hidden field that only bots can see. If this field is filled out, WPForms marks the submission as spam. So it acts like a trap to catch sneaky bots.
Coming to the captcha features, WPForms seamlessly integrates with Google reCAPTCHA and hCaptcha. Turning on captcha is super simple – just a few clicks, and you’re good. No coding needed.
By enabling reCAPTCHA, users will need to check a box to confirm they are not robots before submitting a form. If you don’t want to disturb the user’s experience, WPForms keeps things user-friendly here. You can use an invisible captcha that works in the background, making sure users are real without bothering them.
You can also add a custom captcha field to your forms. This is like creating a puzzle that only humans can solve. Users would be asked to type in letters or numbers, adding an extra layer of verification.
Now setting up is super easy even if you’re brand new to this. You need to register for captcha on Google and get your API keys (a site key and secret key). Then you need to paste those keys in WPForms and save the settings. Follow this tutorial for step-by-step instructions on that: How to Add Captcha.
In the same settings area, you can customize the message if the user fails the captcha challenge. One feature worth noting is the no-conflict mode. If there are issues with other plugins, WPForms has a mode that helps avoid conflicts.
Once captcha is enabled in the settings, you can add it to any form you create with WPForms.
Then you’ll see the badge appear in your form like so:
WPForms is perfect for beginners. You can customize forms with templates, change buttons, set notifications, and make forms smart without any hassle. See our complete WPForms Review for more details.

The easiest way to add Google ReCAPTCHA on your site is to combine it with WPForms. In the WPForms settings in your dashboard, click on the “reCAPTCHA” tab, and you’ll see options to connect with Google reCAPTCHA. Just follow the simple onscreen steps to get your site connected.
