Google Authenticator App : How to use

Google Authanticator

Google Authenticator is a free mobile app that will secure your accounts from password theft. In a method called two-factor authentication (2FA) provided on common services such as Gmail, Facebook, Twitter, Instagram, and more, it is simple to set up and can be used easily.

The App (iOS/Android) creates a random code that is used when you log in to different services to check your identity. Technically, the code can still be sent to your phone via text message, but an extra level of protection is offered by the Google Authenticator app. There is a known security vulnerability in SMS-based 2FA, and any devoted hacker will try to socially engineer an assault against your phone company. Using algorithms to create codes on your phone, the Google Authenticator app removes the risk of an SMS-based attack. 

Here's how you can set it up:

  • From either the Apple App Store or the Android Google Play store, download Google Authenticator which is free!.
  • First, set up your Google account for two-step verification. Sign in to your account with Google. Open the App you will see 2 options, 
    • Scan a QR code
      • Here you can use QR code scanning to get the code with the help of an in-app QR scanner.
    • Enter a setup key
      • In this option you will see options like Account Name, Key a dropdown with an option with whether it’s Time based or counter-based.
        The first option is much more popular than just setting up the Key.
