How to Enable Customer Login or Register Captcha in Magento 2

Spam is every ecommerce store owner’s worst nightmare. It clouds the numbers and adds unnecessary overheads to the store processes. In many cases, if spam goes beyond a set limit, it could be a serious threat to the server resources.

To counter spam, Magento 2 store owners could use CAPTCHA at both registration and login pages for the customers. The good thing is that it is easy to add the filter at both these pages. In this tutorial, I will go over the process of enabling CAPTCHA in Magento 2 customer registration and login pages.

Open the admin panel of your store and then go to STORES → Configuration:

Next, click on Customer Configuration under the CUSTOMERS tab:
Now unfold the CAPTCHA section where you could setup the filter. Here is a short explanation of the fields in the section:

Enable CAPTCHA on Storefront: Select Yes from the drop-down menu to enable CAPTCHA.

Font: Select the font for the CAPTCHA from the list. Forms: Select the forms on which you want to show CAPTCHA.

Displaying Mode: If you want to show CAPTCHA always, select Always from the dropdown menu. If you want to show CAPTCHA after multiple attempts, select After Number of attempts to login.

Number of Unsuccessful Attempts to Login:

CAPTCHA Timeout (minutes): Enter the time after which CAPTCHA will expire, and the user has to reload the page for regenerating the CAPTCHA.
