HOW TO SETUP 2-STEP VERIFICATION USING GOOGLE AUTHENTICATOR.

You must have already setup a 2-step verification before now but if you haven’t, see it here. If you set up 2-Step Verification using SMS text message or Voice call and also want to be able to generate codes using the Android, iPhone or a Blackberry, you can use the Google Authenticator app to receive codes even if you don’t have an Internet connection or mobile service.

This process will put you through how to install Google Authenticator on any of the following devices.

Android

iPhone, iPad or iPod Torch

Blackberry

FOR ANDROID

Requirements

To use Google Authenticator on your Android device, it must be running Android version 2.1 or later.

Downloading the app

Visit Google Play.

Search for Google Authenticator.

Download and install the application.

Setting up the app

If you haven’t already, complete the SMS/Voice setup and enroll your account in 2-Step Verification using your phone number.

On your computer, go to the 2-Step Verification settings page and click on Android.

On your phone, open the Google Authenticator application.

If this is the first time you have used Authenticator, click the Add an account button. If you are adding a new account, choose “Add an account” from the app’s menu.

To link your phone to your account:

Using QR code: Select Scan account barcode (label 1a). If the Authenticator app cannot locate a barcode scanner app on your phone, you might be prompted to download and install one. If you want to install a barcode scanner app so you can complete the setup process, press Install (label 2a) then go through the installation process. Once the app is installed, reopen Google Authenticator, point your camera at the QR code on your computer screen.

Using secret key: Select Manually add account (label 1b), then enter the email address of your Google Account in the box next to Enter account name (label 2b). Next, enter the secret key on your computer screen into the box under Enter key (label 2c). Make sure you've chosen to make the key Time based (label 2d) and press "Save."

To test that the application is working, enter the verification code on your phone (label 3) into the box on your computer next to Code, then click "Verify."

If your code is correct, you will see a confirmation message. Click "Save" to continue the setup process. If your code is incorrect, try generating a new verification code on your phone, then entering it on your computer. If you’re still having trouble, you might want to verify that the time on your phone is correct or read about common issues.
