How to Set Up Microsoft Authenticator Securely

HowToForYou.com – Microsoft Authenticator can help protect online accounts by adding another verification step during sign-in or, in some cases, replacing the traditional password-based process.

The app supports personal Microsoft accounts, work and school accounts, and certain third-party services that allow authenticator apps for two-step verification. It can also be used for passwordless sign-in with a Microsoft account.

Understanding how to set up Microsoft Authenticator begins with choosing the type of account and security method you want to use. The setup process varies depending on whether you are securing a personal Microsoft account, an employer or school account, or another supported online service.

What Is Microsoft Authenticator Used For?

Microsoft Authenticator is a mobile app that can be used in several ways:

• Add two-step verification to an account
• Approve sign-in requests
• Generate one-time verification codes
• Provide an alternative sign-in method for a Microsoft account
• Support passwordless sign-in for eligible Microsoft accounts
• Secure certain non-Microsoft accounts that support authenticator apps

The same app can manage multiple accounts, although the setup process may differ depending on the service.

How to Set Up Microsoft Authenticator for a Personal Microsoft Account

The first step is to install Microsoft Authenticator on an Android phone or iPhone.

After installing the app, sign in to your Microsoft account’s advanced security settings. From there, you can choose how you want to use Authenticator.

Choose Your Preferred Sign-In Method

Microsoft provides three options for using Authenticator with a personal account.

1. Add Authenticator as an Alternative Sign-In Option

This option can provide another way to sign in or verify your identity.

Select Add a new way to sign in or verify, then choose the option to use an app.

Open Microsoft Authenticator, tap the + button, select Personal Account, and choose Scan a QR code. Then scan the code displayed during setup.

2. Turn On Two-Step Verification

Two-step verification adds an additional step when signing in to your Microsoft account.

During setup, you may receive recovery codes. These should be stored somewhere safe because they may be needed if you lose access to your phone.

3. Enable Passwordless Sign-In

Passwordless sign-in allows you to verify access to your Microsoft account with your phone instead of entering a password.

To enable it, locate the Passwordless Account option in your Microsoft account security settings, turn it on, and follow the verification instructions.

The general process is similar across supported services.

Enable Two-Step Verification

4. Allow camera access if prompted.
5. Scan the QR code.

How to Sign In Using Microsoft Authenticator

Once your account is connected, the app can be used as part of the sign-in process.

The exact method depends on the account and the type of verification being used.

Approving a Sign-In Request

For a Microsoft account, you may see an option such as Send notification.

You might also need to select Other ways to sign in and then choose the option to approve the request through Microsoft Authenticator.

Open the notification or the Authenticator app on your phone and verify the sign-in request.

In some cases, you may see a number displayed on the device where you are signing in. Select the matching number in Authenticator and tap Approve.

Using a One-Time Code

Other services may require you to enter a code generated by Microsoft Authenticator.

Open the app, select or locate the appropriate account, and use the displayed code when prompted.

The source material notes that these codes refresh every 30 seconds. If the code changes before it is entered, use the newly generated code.
