Reactive Google Authenticator 

Introduction

Provides secure two-factor authentication to your users. The Reactive Google Authenticator  works by integrating with Google Authenticator, a popular two-factor authentication app that generates one-time passcodes (OTPs) that are used to verify the identity of users trying to access your application.

The Block is designed to prompt users to enter the OTP code generated by Google Authenticator every 30 seconds, and then verify if the provided code is valid or not. If the code is valid, Google Authenticator Block will fire an event that allows the user to proceed with accessing your application. If the code is not valid, the user will be prompted to enter a new code.
