How to Set Up Microsoft Authenticator App in 2026? Step By Step!
Setting up the Microsoft Authenticator app involves installing the app, connecting it to your Microsoft or other accounts, enabling two-step verification, and confirming your login using your mobile device. The app generates secure codes or sends approval notifications whenever you attempt to sign in.
The process works similarly on both Android and iPhone devices, though the interface may differ slightly. You need access to your Microsoft account settings on a computer or mobile browser to complete the setup. Once configured, you can manage all authentication requests directly from the app.
In this guide, you will learn how to install it, link your accounts, enable verification, and use it safely.
How to Set Up the Microsoft Authenticator App?
To set up the Microsoft Authenticator app, install the app from the App Store or Google Play Store, sign in with your Microsoft or work account, and follow the on-screen instructions to link your account using a QR code or verification method. Once connected, enable two-factor authentication and approve sign-in requests directly from the app for enhanced security.
Below is a complete step-by-step guide to help you set up Microsoft Authenticator correctly.
Step 1: Download and Install the Microsoft Authenticator App
The first step is to install the official Microsoft Authenticator app on your smartphone. This app is available for both Android and iOS devices.
Open the Google Play Store if you are using an Android phone or the Apple App Store if you are using an iPhone. In the search bar, type Microsoft Authenticator and press search. Make sure the app is published by Microsoft Corporation to avoid downloading fake or harmful apps.
Tap the install button and wait for the app to download and install on your device. Once installation is complete, open the app from your home screen.
When you launch the app for the first time, you will be asked to accept permissions. Allow notifications and camera access because these are required for receiving login approvals and scanning QR codes during setup. Without these permissions, the app may not work properly.
Step 2: Sign In or Add an Account
After opening the app, the next step is to add your account. You can use the Microsoft Authenticator for personal Microsoft accounts, work accounts, and other supported services.
Tap the option that says Add account. You will see different account types such as Microsoft account, work or school account, and other account options. Choose the one that matches your account type.
If you select a Microsoft account, you will be prompted to sign in using your email address and password. Enter your credentials carefully and continue. If you select a work or school account, you may need to sign in with your organization credentials.
Once signed in, the app will ask for confirmation to connect your account. Follow the on-screen instructions to proceed. This step ensures that your account is securely linked to the app.
Step 3: Open Microsoft Security Settings on Browser
To fully enable authentication, you must access your Microsoft account security settings through a web browser. This step is essential for enabling two-step verification.
Open a web browser on your computer or smartphone and sign in to your Microsoft account. After logging in, go to the Security section of your account dashboard. Look for an option called Advanced security options or Additional security.
In the security settings, locate the option for two-step verification or multi-factor authentication. Click on it to begin the setup process. Microsoft will guide you through a series of prompts to connect your account with the authenticator app.
Keep your phone with the Microsoft Authenticator app open during this step because you will need it to scan a QR code.
Step 4: Scan the QR Code
During the setup process on the Microsoft security page, you will see a QR code displayed on your screen. This QR code is used to connect your account securely with the authenticator app.
Open the Microsoft Authenticator app on your smartphone. Tap Add account and select the appropriate account type. Choose the option to scan a QR code.
Your phone camera will open automatically. Point the camera at the QR code displayed on your computer or browser screen. Make sure the code is clearly visible within the frame. The app will scan and detect the code automatically.
Once the QR code is scanned, your account will be added to the Microsoft Authenticator app. You will see your account name appear in the app with a verification code or approval option.
Step 5: Verify the Connection
After scanning the QR code, Microsoft will ask you to verify that the connection is working properly. This is done by sending a test notification or code to your authenticator app.
Check your phone for a notification from Microsoft Authenticator. Open the notification and approve the sign-in request. If a code is displayed instead, enter the code into the verification field on your browser.
Once verified, your Microsoft account will be successfully linked with the authenticator app. This means you will now receive approval requests or verification codes whenever you sign in.
Step 6: Enable Two-Step Verification
The most important part of setting up Microsoft Authenticator is enabling two-step verification. This ensures that every login attempt requires approval from your device.
In your Microsoft security settings, turn on the option for two-step verification. Follow the instructions provided on the screen. Microsoft may ask you to confirm your identity again using your password or a code sent to your email or phone.
After enabling two-step verification, every time you sign in to your Microsoft account on a new device, you will receive a notification in the Microsoft Authenticator app. You must approve this request to complete the sign-in.
This extra layer of protection keeps your account safe even if someone else knows your password.
Step 7: Set Microsoft Authenticator as the Default Sign-In Method
To make your login process smoother and more secure, you can set Microsoft Authenticator as your default sign-in method.
Go back to your Microsoft account security settings. Look for an option called Additional security verification or Default sign-in method. Select Microsoft Authenticator from the list.
By setting it as the default, you will receive push notifications for login approvals instead of entering codes manually. This makes signing in faster and more convenient while maintaining strong security.
Step 8: Add Backup and Recovery Options
It is always important to have backup options in case you lose access to your phone. Microsoft allows you to add backup methods such as phone numbers or alternative email addresses.
In the security settings, add a backup phone number and email address. This ensures you can recover your account if your device is lost, stolen, or reset.
You can also enable cloud backup within the Microsoft Authenticator app. This feature allows you to restore your accounts if you switch to a new phone. Make sure to sign in with your Microsoft account in the app to enable backup.
Step 9: Test the Authenticator App
After completing the setup, it is a good idea to test the app. Sign out of your Microsoft account and then sign in again.
Enter your email and password as usual. You should receive a notification on your phone from the Microsoft Authenticator app asking you to approve the sign-in. Tap approve to complete the process.
If the login is successful, your authenticator app is working correctly. You can now use it for secure sign-ins across Microsoft services and other supported platforms.
