How to Enable CAPTCHA for Admin Login in Magento 2

Generally, Magento 2 owners focus so much on customer security that stays on the frontend; they often neglect the importance of having security for the backend side.

Having amazing security in Magento 2 website for admin login is very important because the complete website handling is being done from in the backend using the admin panel.

To safeguard your Magento 2 frontend forms from spam and bot attacks, you can add Google RECAPTCHA in Magento 2. Backend or admin login security is as important as frontend and default Magento 2 provides the facility to improve the security of the admin login by enabling captcha. Even if the admin tries to hit the login button multiple times, the admin user has to enter captcha to login to the Magento 2 admin panel.

According to Wikipedia, A CAPTCHA – Completely Automated Public Turing Test to tell Computers and Humans Apart, is a type of challenge-response test used in computing to determine whether or not the user is human.

In general terminology, CAPTCHA is a program that distinguishes human from the machine input basically to stop spams from extracting data from a website.
