Are you looking for a way to protect your WordPress site from spam and bots? If you have a form or a comment section on your site, you need a WordPress captcha plugin. A captcha plugin will help you block spam comments and form submissions from bots. It will also prevent hackers from trying to break into your site or harm your users.
But what is captcha and how does it work? Captcha stands for “Completely Automated Public Turing test to tell Computers and Humans Apart.” It is a type of challenge-response test that can verify if the user is a human or a computer. There are different types of captcha available, such as text captcha, image captcha, audio captcha, math captcha, puzzle captcha, and more.
Captcha is important for any website that has user input fields, such as blogs, forums, online stores, or membership sites. Captcha can help you prevent malicious attacks, such as SQL injections, cross-site scripting, or brute force attacks. It can also help you prevent spam comments and fake registrations that can affect your site’s performance and reputation.
However, adding captcha to your site can be tricky. You need to create an API key and add a secret key and site key to your plugin settings. You also need to choose a captcha plugin that is compatible with your WordPress theme and plugins. To help you with that, we have compiled a list of the best WordPress captcha plugins and tools that you can use on your site. Let’s take a look at them.
