Protect your E-mail via Google Authenticator
Google Authenticator is a free security application that helps protect your account against theft of passwords. It’s easy to install and can be used in a process called 2-factor Authentication (2FA) that is offered in popular services such as Gmail, Facebook, Twitter, Instagram, and more.
The app (iOS / Android) generates a random code used to verify identity when accessing multiple services. The code can be sent technically to the phone via a text message at a time, but the Google Authenticator app provides an additional security level.
The SMS based 2FA has a known security flaw and any devoted hacker can attempt to Socially engineer an attack against his Mobile company. The Google Authenticator app eliminates the possibility of an SMS-based attack using algorithms to generate codes on your phone.
Here’s how to set it up:
- Download the Google Authenticator from Google Play Store or Apple App store. It is free.
- Next, set up, two-step verification in your Google Account. Sign in to your Google account. Under “Security and Access,” select “Two-Step Verification” and scroll down to select the “Authenticator Application” option.
- Select your phone, Android or iPhone.
- Open the real Google Authenticator application on your phone and tap the +button:
- There are two options in the bottom of the screen: “Scan Barcode” and “Manual entry”.

Just choose one of these options to complete the process. The Option of “Scan Barcode” takes a bit longer to complete, requiring downloading a QR scanner from the application store, and then pointing the phone to the QR code on the computer screen to verify the Authenticator connection with your account .
Conversely, “Manual Entry” means only that Google will send you a 16-digit code to an e-mail address. Enter the code to specific location and complete the verification process:
Make sure the “Time-Based” option is enabled so that the code you are entering is aligned with the most recent Authenticator access code generation.
Now, whenever you sign in to the account you connected to Google Authenticator, your account will ask you to enter a six-digit verification code. Simply open the Google Authenticator app and the application will generate the new random access code.
(Remember, if you stay in touch, you do not have to go through the 2-FA process during each login.
Congratulation! Your account is not only securing with two-factor authentication, but with additional six-digit authenticator code protection from Google.
