How to use the Google Authenticator app with Multifactor Authentication

How to use the Google Authenticator app with Multifactor Authentication


Because it’s free and widely available on Android, iOS/Apple, BlackBerry, and Windows mobile devices, as well as other third-party APIs/Apps, the Google Authenticator software was chosen. Consider the following scenario:

Rails Python HTML5 WordPress Login Plugin
Here are the full details on Google’s security methods and implementations:
With a cellular or Internet connection, Google Authenticator is especially handy on mobile tablets and phones. Google Authenticator additionally gives a list of non-expiring backup codes (during the first setting) that can be utilized in the event of a lost or disconnected mobile device. The 2nd layer code can be obtained outside of the Google Authenticator app via SMS text message or phone calls.

Getting the Google Authenticator App

Install the Google Authenticator software on your smartphone or tablet device before you can enable Multifactor Authentication on your GreggHost account.

If you already have the Google Authenticator app on your phone or tablet, simply click the “+” in the lower right corner (iOS) or go to the app’s settings and select “Add account” (Android). Then move on to the next step of this guide.

The official Google documentation for downloading and installing the app is available here:

The app can be downloaded via the App Store on your smartphone (or from Google’s direct link for BlackBerry users):

Android phones and tablets: Google Play is a search engine that allows you to
Whether it’s an iPhone, iPad, or iPod Touch, there’s a device for you. App Store on iTunes

Enabling MFA in the panel for Google Authenticator

Go to the Security section of the website.
Multifactor Authentication: 01 MFA.png is the second section on that page.
Password in Use: Enter the password for your GreggHost account.
Type of Multifactor Authentication: To use one of the two Google techniques, select one from the dropdown menu:
– Time-Based Google Authenticator (preferred) – Counter-Based Google Authenticator
GreggHost advises using one-time passcodes that are time-based. Because each code is only valid for a limited period of time, time-based codes give improved security against phishing and keyloggers. In contrast to counter-based codes, which require manual synchronization, time-based codes automatically stay in sync with GreggHost’s servers.

To progress to the next code if you use counter-based codes, tap the refresh button next to the code in the Google Authenticator App each time you use it.
To get started, click the Get Started button.
You’ll see a QR code and a 16-digit secret key to activate Multifactor Authentication:

Scan the QR code with the Google Authenticator app.
You can manually enter the 16-digit secret key given below the QR code into the app if your device does not have a camera.
Scanning the QR code or entering the key on each device you want to use with your GreggHost account is required if you have more than one device running Google Authenticator.
Enter the 6-digit passcode displayed by the Google Authenticator app into the passcode field.
You may need to use the refresh button to see the first code if you’re using counter-based codes.
The GreggHost server is linked to your smartphone after you click the Activate! button.
A ‘Success!’ confirmation box appears next:

The backup codes in the ‘Success!’ dialog box should be saved. If you’re using Google Authenticator and fear your account has been hacked (for example, if you’ve lost your phone or mobile device), you can click the Regenerate Key button to invalidate the old key and produce a new one.
Select ‘Encrypt iPhone Backup’ to back up the Google Authenticator account when backing up an iPhone to your local computer (s). Otherwise, when Google Authenticator is restored, it will have no accounts linked with it.

What if I need a new phone?

If you’re buying a new phone, ensure sure Multifactor Authentication is turned off in your control panel. On the Security page, you can do so. Enter your password and disable Multifactor Authentication under the Multifactor Authentication option.

Log back into your panel and set up your new phone as described above once you’ve received it.
