Implement Captcha

LoginRadius Identity Platform provides you the feature to add another layer of security to your registration form by configuring CAPTCHA, which ensures that the person registering is not a bot.

Note: CAPTCHA is mainly used as a security check to ensure only humans can pass through. Generally, bots are not capable of solving a captcha.

As a part of your Login and Registration flows, LoginRadius CAPTCHA settings allow you to enable Google reCaptcha, which is a service from Google that protects web applications from spam and abuse. It is easy for humans to solve, but hard for “bots” and other malicious software to figure out.

Currently, LoginRadius supports two different versions of the Google reCAPTCHA.

  • reCAPTCHA v2: This is the second version of the reCAPTCHA service. With this, consumers are presented with descriptions along with a set of images to identify based on the description.
  • Invisible reCAPTCHA: This version provides a better experience to the consumers by tracking mouse movements to identify if a human is interacting with the application or it is a bot. If identified as a bot, it displays the CAPTCHA option on the screen.

Note: You can select one of the reCAPTCHA options while configuring CAPTCHA settings in Google.

The following explains the configuration and deployment of the above CAPTCHA features:
