Enable Magento 2 Captcha for Customer Login (1)

Are you looking to enable Magento 2 captcha for customer login and registration form?

Magento 2 comes with the prebuilt captcha configuration. So you do not have to install any extension to add a captcha.

Within a few clicks, the admin can enable it. This quick tutorial will show you how to add a captcha to the Magento 2 store.

What is Captcha?

Captcha is short for a Completely Automated Public Turing test to tell Computers and Humans Apart. It is a tool to tell the difference between real human users and robot crawlers.

There are so many bots roaming the internet. They move from one webpage to another, following the links. 

However, if there is a captcha, they will be required to enter a string of text, character, or number displayed in the box to continue forward. The captcha tool morphed these characters in a way that robots cannot read them. Humans can easily understand the disfigured characters, though.

By this simple trick, the captcha prevents the bots from entering the website.

Why use captcha?

Not all the bots are good. 

An eCommerce store uses analytic bots for marketing purposes and third-party bots to add functionalities. But hackers also use them to steal customer information, fake registration, DDoS attacks, Brute Force Attacks, etc.

Then some people run scripts to buy the products during sales, leave spam comments and fill the forms with spammy information.

By using captcha, you keep the website secure from such practices.
