Microsoft Authenticator App on New Phone: A Step-by-Step Guide

Are you switching phones and need to set up two-factor authentication (2FA) on your Microsoft authenticator app? This process may seem daunting, but it's actually quite straightforward. In this article, we'll walk you through the steps to ensure a smooth transition.

Deauthorizing Your Device

Before starting the process, make sure to deauthorize your device by following these simple steps:

1. Sign in to your Microsoft account and click on your name in the top right corner.

2. Choose 'My Profile' from the dropdown menu.

3. Click on 'Trusted Devices' to view the list of authorized devices.

Setting Up 2FA

To set up two-factor authentication, follow these steps:

1. Open the authenticator app on your new phone and use it to scan the QR code provided by Microsoft.

2. If you don't have a backup of your 16-character secret key, write it down and store it safely, such as with your passport or in an emergency kit.

Confirming Your Code

After scanning the QR code, you'll receive a six-digit authentication code. Enter this code on the Microsoft website to confirm that your authenticator app is set up correctly.

Additional Tips

If you have a security key, such as YubiKey or Titan, you can use it as an additional factor for 2FA with your Microsoft account. To do so:

1. Sign in to your Microsoft account and click on your name in the top right corner.

2. Choose 'My Profile' from the dropdown menu.

3. Click on 'More Actions > Manage Two-Factor Authentication.'

By following these steps, you'll be able to set up two-factor authentication using your Microsoft authenticator app on your new phone. Remember to keep your 16-character secret key safe and secure to ensure maximum protection for your account.
