What is Captcha Code?
CAPTCHA code was created to stop automated computer spam robots from filling out forms, harvesting email addresses, and then sending out countless spam emails.
The CAPTCHA security image works by asking the website visitor to type in a code they see correctly. A human can do this, but an automated computer program cannot.In wordpress there are so many free wordpress plugins are available. Here in this article I am going to tell you, how to use captcha code in wordpress website.
Captcha (https://wordpress.org/plugins/captcha/)
The Captcha plugin allows you to implement a super security captcha form into web forms. It protects your website from spam by means of math logic, easily understood by human beings. You will not have to spend your precious time on annoying attempts to understand hard-to-read words, combinations of letters or pictures that make your eyes pop up. All you need is to do one of the three basic maths actions – add, subtract and multiply. This captcha can be used for login, registration, password recovery, comments forms. There is also a premium version of the plugin, allowing compatibility with BuddyPress (Registration form, Comments form, “Create a Group” form) and Contact Form 7.
SI CAPTCHA Anti-Spam (https://wordpress.org/plugins/si-captcha-for-wordpress/)
Adds CAPTCHA anti-spam methods to WordPress forms for comments, registration, lost password, login, or all. In order to post comments or register, users will have to type in the code shown on the image. This prevents spam from automated bots. Adds security. Works great with Akismet. Also is fully WP, WPMU, and BuddyPress compatible.

3. WP Captcha-Free
WP Captcha-Free blocks automated comment spam without resorting to CAPTCHAs. It does so by validating a hash based on time (and some other parameters) using AJAX when the form is posted. Comments posted via automated means will not have a hash or will have an expired hash and will be rejected. Unlike using a captcha, this does not place any burden on the commenter.
4. Raz-Captcha

5. Really Simple CAPTCHA
Really Simple CAPTCHA does not work alone and is intended to work with other plugins. It is originally created for Contact Form 7, however, you can use it with your own plugin.
Note: This product is “really simple” as its name suggests, i.e., it is not strongly secure. If you need perfect security, you should try other solutions.
6. WPMU Super CAPTCHA
This plugin was developed primarily for the WordPress Muti-User edition and now works with Buddypress, however it works on the regular single domain version as well. It combats spam bots from flooding you with sign-ups and blog creations and it keeps bots from brute- force attacking your site with the admin username by forcing a visual confirmation CAPTCHA in order to login. Most CAPTCHA systems for WordPress gives you a very templated layout and read-out, many that can be programmed into a bot to bypass. With Super CAPTCHA, you can personalize and control the very way the CAPTCHA is rendered so every site that displays the CAPTCHA will be diffrent, making it so each bot has to be pre-configured, just for your site, in order to achieve a successful attack making Super CAPTCHA the MOST SECURE free anti-spam system available for WordPress.
