A large number of people are converting HTML to WordPress or migrating websites from other formats. Their main objective is to get an easily manageable and secure interface. In this article, we are presenting a list of the best plugins for adding Captcha to WordPress. This will help people in making their interfaces even safer. Captcha is the acronym for Completely Automated Public Turing Test to Tell Computers and Humans Apart. This test is used as a protective measure to differentiate between machines and humans. The need for such a mechanism arose after unscrupulous elements started spamming websites through bots. Computers cannot complete a captcha which means that WordPress bloggers can use the feature to prevent spam on their interfaces. Following are the best free captcha plugins that they can use:

The Conditional Captcha comes with two modes- basic and Akismet-enhanced. The basic version shows the code to visitors without a previously approved comment and who are not logged in. The other mode works only if the Akismet plugin is activated on the website. It is more efficient as it displays the captcha only if Akismet marks a comment as spam. The default test of the product is text-based but people can use Google’s reCAPTCHA through an API key.
