How To Add CAPTCHA Protection to WordPress
WordPress is one of the most popular content management systems (CMS) in the world, powering over 40% of all websites on the internet. However, with great popularity comes great responsibility. WordPress sites are often targeted by hackers and spammers, which can lead to devastating consequences for website owners.
One way to protect your WordPress site from spam and bots is by adding CAPTCHA protection. CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a security measure that requires users to prove that they are human by completing a simple task, such as typing in a series of letters or numbers.
In this article, we will discuss how to add CAPTCHA protection to your WordPress site.
Why Do You Need CAPTCHA Protection?
Spam and bots can cause a lot of problems for your WordPress site. They can overload your server, slow down your website, and even crash it. They can also negatively impact your search engine rankings and damage your reputation.
Spammers and bots use automated software to create fake user accounts, leave spam comments, and send spam emails. They can also use your contact forms to send spam messages or even inject malicious code into your website.
CAPTCHA protection can help prevent these types of attacks by verifying that the user is human. It adds an extra layer of security to your website and makes it more difficult for spammers and bots to infiltrate.
