Setup Microsoft Account to work with Google Authenticator.

Although Microsoft has its app called Microsoft Authenticator, many people prefer to use Google Authenticator instead. Apps are fairly similar to each other but Google Play store downloads statistics suggest that the Google version of the app is far more popular.

If you are new to the Google Authenticator app, it is also worth mentioning that the latest version of the app brings a long-awaited feature called Transfer Accounts. For me, the lack of this option was a deal-breaker before the update.

Although I was using the Google Authenticator app even without this option, I have decided to have a backup option which is called Authy. You can read here about the differences between the Authy and Google Authenticator which will give you an idea of why I choose Authy as my main 2FA app.

If you like a dedicated solution, including an advanced Password Manager, why not try 1Password – Password Manager.

In my opinion, 1Password is the best Password Manager currently available and it has a Two Factor Authenticator build into it. It will not only automatically populate both login and password for you but also the Two Factor Authentication code once set in the app.

You can try 1Password for free or check the latest offers on the 1Password website.

Save the Secret Key.

Saving your Secret Key although unnecessary I consider as crucial, you will have only one chance to do this and may save you a lot of headache in the future.

What is a Secret Key?

The Secret Key is a 16 characters long Alpha-Numeric code that you can use anytime to pair your Microsoft Account with Google Authenticator or any other Two-Step Verification app without a need for the barcode.

For example, after you complete this process and set up your Google Authenticator app to work with your Microsoft Account there might be a time when you would like to set up another phone.

As of writing this article, the newest version of the Google Authenticator app offers an Account Transfer option which will allow you to transfer selected accounts to your new phone.

This is great, but what will happen if you lose your phone with Google Authenticator on it?

This is the problem you don`t want to deal with, believe me. That’s where the Secret Key comes to the rescue. And yes you can just use your Recovery Code to access your Microsoft Account and reset the Google Authenticator app again.

I think however that it is much quicker to just grab your new phone, install Google Authenticator, Microsoft Authenticator, or Authy for example, type your code and you are ready to go.

The only difference is that instead of scanning a barcode that you don`t have, you type the Secret Key instead to re-link your account, and you are done.

You can read more about the Secret Key or Recovery Codes in my other article Google Authenticator – How to add an Account?.

Where do I find the Secret Key?

To view the Secret Key make sure to click I can`t scan the barcode link.

Now you can copy the Secret Key but make sure to save it in a secure location. I keep all my sensitive information in my trusted Sticky Password password manager.

6) Scan the QR Code with your Google Authenticator app.

Once is done, click I`ll scan a barcode instead link if you haven’t done so yet and complete the process by scanning the barcode. Finally, verify that the process was completed successfully by entering a code generated by Google Authenticator app to the field below and by pressing next.

7) Save the Recovery Code.

The final step is to save your Recovery Codes.

What is a Recovery Code?

If you lose your phone and you haven`t saved your Secret Key, the Recovery Code will be the only way to access your Microsoft Account. As with the Secret Key make sure to keep this code in a safe place.

Where do I find the Recovery Code?

Go back to your Security Settings, scroll almost all the way down, and click Replace Recovery Code. This will reveal the code which you should copy and store in a safe place.

Remember that this is a one-time use code so you need to visit this place every time and replace your recovery code if you have used the previous one to access your account.

Finally press OK and you are done.

From now on you can have peace of mind that you have secured your Microsoft Account using the latest and safest technology available at the moment.

By saving the Secret Key and the Recovery Code you can be sure that in case of a problem you can always access your account or set up the Google Authenticator app on your new phone.

My Favorite Software and Hardware.

Thank you for reading this article. I hope you found it helpful. Here is the list of the software and hardware I am personally using, which I believe you may also find useful. These are affiliate links, so if you decide to use any of them, I will earn a small commission at no extra cost to you. But in all honesty, this is the exact software I have installed on my computer and the hardware I have been using to secure my online accounts or store my passwords.

1Password Password Manager - I have been using 1Password for over three years now, and in my opinion, it is the best Password Manager yet. You can try 1Password for free or check the latest deals on the 1Password website.

YubiKey - This is a hardware authentication device that you can use to protect your online accounts or even computers. If you are thinking of getting one, I will highly recommend Yubikey 5C NFC, which, thanks to the NFC, can also be used with your phone. If you are an Apple user, the YubiKey 5Ci is the best next choice, in my opinion.

Bitdefender Total Security - I had tried other Anti-Virus software whenever my Bitdefender license was about to expire. However, at the end of the day, this is still my favorite Anti-Virus. You can check the latest offers on the Bitdefender site.
