How to setup Google Authenticator and two-factor authentication


Two-factor authentication is an important tool for securing your accounts and protecting your data online.


Google Authenticator is an excellent free tool that you can use to ensure your online accounts are secured. This is a two-factor authentication system that enables a second step on your logins for an extra layer of security.


Even the most secure passwords can still be compromised by hackers or social engineering, but they can’t also access your phone for that one-time code.

So Google Authenticator is an excellent tool to add to your arsenal and protect yourself online, but how do you use it? We’re here to show you how.


How does Google Authenticator work?

On many modern apps and some websites, you’re often given the option to activate two-factor authentication (also known as 2FA). You’ll usually find this within the security or login settings and when turned on it will add a second step to your login process.

When fully set up the next time you log in to the app or service you’ll need to not only enter your username and password, but also a time-limited code that’s generated by the Google Authenticator app.

Google Authenticator is one of several 2FA apps out there and it’s the most common one used by many apps and services. It’s free and it’s easy to use, plus it’s readily available on any Android smartphone or Apple iPhone.

How to set up Google Authenticator

Naturally, the first step to using Google Authenticator is to download it.

The next step is to connect it to any (and all) relevant accounts that you want to use it with. We’d highly recommend using a secure password along with Google Authenticator to ensure your important accounts are doubly secure.

To do this you’ll need to head over to the security or login settings on the app or service you’re using. From there you’ll hopefully find a 2FA option that you can turn on.

When you turn on two-factor authentication settings you’ll be prompted to connect your account to Google Authenticator. To do this you’ll need to press the plus icon on the bottom right of the app, then scan a QR code with the authenticator app.

This process connects your accounts together. Then when you next log in you’ll be prompted for the 2FA code. So you’ll need your phone to hand and the Google Authenticator app at the ready.

Load the app and you’ll then need to find the relevant site listed within it. There should be a six-digit numerical code there along with a timer. You have a short period of time to copy that code into the site or app you’re trying to access. When the timer runs out a new code is generated, so don’t worry you can always just use the new code.

The two-factor codes generated by the Google Authenticator app are linked to your specific app and your phone. So they cannot be accessed by anyone else.

How to move Google Authenticator to a new phone

Once you’ve been using Google Authenticator for a while you’ll find you’ll add a lot of different accounts to it. If you then need to move to a new phone, don’t worry it’s fairly easy to move your accounts across too.

It’s now possible to move an entire Google Authenticator account to a new smartphone without having to move each account individually.

  1. Open the Google Authenticator app on your current phone and click on the menu button on the top right
  2. Then press “transfer accounts”
  3. Then choose “Export accounts”
  4. Click all the accounts you want to export and then press next
  5. That will then generate a QR code (or two) that can be scanned
  6. Open the app on your new phone
  7. Click the same menu button your did before and click transfer accounts
  8. Then press import accounts
  9. Scan the QR code on your old phone with your new one
  10. Import all accounts into your new phone

It’s worth noting that this process works with Android and Apple iPhones. Even if you’re switching from one to the other. Once completed you can uninstall the app on your old phone or do what you need to reset it. Then just carry on using Google Authenticator on your new device with ease.
