5 WordPress Captcha Plugins to Add Captcha to WordPress Blogs

WordPress Captcha

Are you looking for WordPress Captcha Plugins?

Using WordPress for your blog gives you better control of your website and makes it easy to manage everything. But it also makes your website vulnerable to spammers. Within a few days of making your website live, you will start seeing spam comments, spam registration, and spam guest posts in your blog. So, I personally advise you not to allow any person to register and submit posts. Similar thing for comment. You will see hundreds of spam comments daily on your blog. Another big problem is the login brute force. Most hackers use this method to crack the password of a WordPress blog. So, you should also keep your login pages secure. In my previous post, I wrote how to keep your blog secure from Brute forcing attacks and also posted a few security plugins for WordPress.

In this post, I am going to write about a different approach to reducing spam on your blog. You can try adding captcha in the different forms on your blog. Although, it is not very helpful in registering spam. But it will surely help you in reducing the comment spam and limit login brute-forcing.


CAPTCHA is the short form for “Completely Automated Public Turing Test to Tell Computers and Humans Apart.” It is used to differentiate between humans and computers. Captcha in a form helps in preventing bots from submitting the form.


WordPress has several public forms including login, signup, password reset, and comments. Most of the spammers push spam comments automatically on WordPress-based websites for backlinking. Captcha can help in preventing such attempts.

In this post, I am posting a few nice WordPress Captcha plugins which are available for free. You can use any of these WordPress plugins to add captcha to WordPress Login, Registration, or Comment Forms.

Wrap Up

I personally do not use captcha because most people hate it. Even I also hate filling out a captcha. So, you should try to use some alternate way.
