How to Fix Microsoft Authenticator QR Code Not Scanning on iPhone

Product: Microsoft Authenticator
Device & OS: iPhone (iOS)
Scenario: Setting up multifactor authentication for a software program via a provided QR code.
Observed behavior: The camera opens but fails to respond or scan the QR code, preventing the user from completing the account setup.

Before you start

Ensure your iPhone's camera lens is clean and verify that you have granted Microsoft Authenticator permission to access your camera in the iOS Settings app.

Solution 1Recommended

Update the App and Verify the QR Code

Outdated apps or expired QR codes are the most common culprits for scanning failures.

Keeping the authenticator app updated ensures maximum compatibility with newer QR code formats and bug fixes.

Check for updates

Open the Apple App Store on your iPhone, search for 'Microsoft Authenticator', and tap 'Update' if a new version is available.

Test the camera

Attempt to scan a different QR code to verify if the camera and app are working correctly. If another code works, the original code may be expired or invalid.

Invalid QR Codes: If the camera works for other codes but not the one provided by your software, contact the software provider for a newly generated QR code.

Solution 2

Manually Add a Non-Microsoft Account

If the QR code remains unresponsive, you can bypass the camera by entering the setup key manually.

Solution 3

Sign In Directly for Microsoft Accounts

For Microsoft accounts, you can authenticate directly without needing a QR code.
