There are a ton of different solutions available for adding security to your WordPress forms, but a lot of times they either don’t work well, or are complicated to use and install. With the Really Simple CAPTCHA plugin, you can add a form to your sites that is not only easy for you to use and install, but also easy for your users to navigate. The plugin was originally developed by the creators of the immensely popular Contact Form 7, and while the CAPTCHA plugin was designed to be used seamlessly with that contact form 7 plugin, it can also be used easily and simply with any other WordPress form plugin.
The CAPTCHA plugin gives the user an image that they have to then input into the CAPTCHA section of the form — the image usually contains 4 characters and is very legible and not at all hard to read and interpret like many other CAPTCHAs out there. This popular plugin is easy to use for all involved, super lightweight, and has a quick install. It’s not super complicated because it doesn’t provide 100% airtight security, so if that’s what you’re looking for, you may want to continue your CAPTCHA search, but if you just want a simple CAPTCHA that keeps the bots away, this one will mostly get the job done.
