Amid threats of hacking and password theft, Google has introduced a free security app to protect your email account.

Google Authenticator generates 2-Step Verification Codes on your phone. You can learn more about the 2-Step Verification here.

The 2-Step Verification is offered on Gmail and social media platforms like Facebook, Twitter, and other sites.

The app is compatible with all devices – iOs and Android.

Stronger Security

Google said 2-Step Verification “provides stronger security for your Google Account by requiring a second step of verification when you sign in.”

In addition to your password, you’ll also need a code generated by the Google Authenticator app on your phone.”

Mashable said the code generated by the app “is used to verify the identity of the email account owner when logging into various services.”

The code can technically be sent to your phone via text message every time – but the Google Authenticator app provides an extra level of security.”

Since SMS-based 2FA has a known security flaw, according to Mashable, a hacker can attempt to engineer an attack against a phone company.

But Google Authenticator eradicates the chance of an SMS-based attack with the use of algorithms to generate the codes on your phone.


Among the features of 2-Step Verification is generation of verification codes even without data connection, support for Android Wear, and automatic setup via QR code.

A phone camera is needed to add accounts using QR codes.

Setting Up Google Authenticator

You can download Google Authenticator from either Google Play or Apple App store.

Just follow the step-by-step installation of the app here.

Time-Based Option

Make sure that that the “Time-Based” option is “On” to ensure that the code is aligned with the Google Authenticator’s most recent passcode generation.

Each time a Google account user is logged on, the user is connected with Google Authenticator, and the account will ask the user to enter a six-digit verification code.

The user opens the Google Authenticator app, which will generate a new, random code for the user to enter.

A user who stays logged in won’t need to go through the 2-Step Verification process with each login.
