Get Your Phone Set Up with Microsoft Authenticator

Step 1Find the Microsoft Authenticator App

Finding the real Microsoft Authenticator app in your phone’s app store serves as the first step. Authenticity matters to avoid malicious copies.

For iOS (iPhone and iPad) Users:

You can download Microsoft Authenticator setup files on an iPhone or iPad by opening the App Store. Search for Microsoft Authenticator and pick the official app by Microsoft Corporation, which has a blue icon with a shield and the letter ‘A’. Check the developer name to make sure you have the right app before you tap get.

Always double-check the download source.

Direct links to download the app from your device's app store remove guesswork. Here are the shortcuts:

For Android Users:

You can complete your Microsoft Authenticator setup on an Android phone by opening the Google Play Store. Search for the app and pick the official version made by Microsoft Corporation, shown by a blue shield icon with an 'A'. Always check the developer name so you do not download a fake app.

The official Microsoft Authenticator app appears in search results. It carries the blue icon featuring the 'A' and shield. Confirming "Microsoft Corporation" as the developer prevents mistakes.

Sourcing downloads from alternative websites risks introducing malware to your device.

Step 2Launch the App and Get Started

Microsoft Authenticator app setup begins immediately after installation. Launching the Microsoft Authenticator app starts the account protection process. On-screen instructions guide users through adding accounts and securing them.

Opening on iOS:

You need to open Microsoft Authenticator on your iPhone by tapping its icon on your home screen or app library. When the app asks for permissions, allow access to your camera and notifications. Camera access lets you scan setup codes, and notifications give you instant sign-in alerts on your screen.

Granting these permissions ensures the best possible experience with the authenticator app.

Opening on Android:

You can open Microsoft Authenticator on your Android device by finding its icon in your app drawer or home screen and tapping it. Allow camera access so you can scan QR codes, and turn on notifications to receive quick sign-in alerts when you try to log into your accounts.

Android phones request permissions much like iOS devices do. Allow camera access if you plan to use QR codes, and enable notifications so sign-in alerts arrive immediately.

Warning: Denying necessary permissions breaks certain app features. Declining camera access prevents scanning QR codes for quick account additions.

Step 3Add Your Accounts (The Fun Part!)

Connecting your Microsoft accounts to the Authenticator app forms the main event. Multiple methods exist, but scanning a QR code remains the most common approach.

Adding Accounts Manually:

You can add accounts manually in Microsoft Authenticator by typing a secret key from the service if the QR code scanner fails. Open the app, choose to add an account, pick the account type, and select enter code manually. Type the code and account name given by the website you want to protect.

Recovery codes grant access to accounts if a phone or Microsoft Authenticator app gets lost. Store these crucial recovery codes in a secure location. Losing these codes makes regaining access to accounts impossible.

Step 4Configure Two-Step Verification

You must turn on multi-factor authentication (a security system requiring two or more forms of verification) in your service security settings after adding your account to Microsoft Authenticator. Go to the security page of the website or email service you want to protect, find the sign-in settings, and turn on the prompt approval feature.

Return to the security settings of the Microsoft account or service you are protecting. Turning on 'two-step verification' (also known as multi-factor authentication [MFA]) adds another layer of security. Selecting "Authenticator app" as the verification method occurs during this configuration.

A test notification arrives on your phone through the Authenticator app. Approving a sign-in attempt completes the test. Successful completion confirms proper connectivity.

Warning: Never turn off two-step verification unless absolutely necessary. This control remains one of the best defenses against unauthorized account access.

This guide covers setting up Microsoft Authenticator on your smartphone, spanning from app installation to account linking and two-step verification enablement.
