Fix Microsoft Authenticator Frozen on iPhone Unlock Screen
Question details
Microsoft Authenticator becomes completely unresponsive and gets stuck on the unlock screen on iOS devices, even after successful Face ID or PIN verification.
- Product
- Microsoft Authenticator
- Device & OS
- iOS
- Scenario
- Attempting to open the Microsoft Authenticator app to view account codes or approve a sign-in request on an iPhone.
- Observed behavior
- The app authenticates via Face ID or PIN but remains frozen on the Unlock screen. Touch input is not recognized, and standard troubleshooting like reinstalling or restoring accounts does not permanently resolve the issue.
Before attempting any fixes, ensure you have alternative backup authentication methods (such as SMS codes, a backup email, or physical security keys) configured for your Microsoft accounts to prevent a total lockout.
Approve Authentication Notifications with the App Closed
Use this temporary workaround to bypass the frozen unlock screen by triggering an authentication prompt from a computer while the app is force-closed on your iPhone.
Since the app UI freezes upon manual launch, you can interact directly with the iOS push notification system to approve sign-ins without fully opening the application. Note that this clears the locked screen temporarily, but the freeze may return the next time you open the app directly.
Swipe up from the bottom of your iPhone screen to open the app switcher, find the Microsoft Authenticator app, and swipe up on it to force close it completely.
Open a web browser on your computer (such as Edge, Chrome, or DuckDuckGo) and attempt to sign in to your Microsoft account.
When the computer prompts you to verify your identity, select the option to send a notification to your Authenticator app.
When the push notification appears on your iPhone lock screen, long-press or tap it to approve the sign-in directly from the notification banner, without launching the actual app.
Document App Details and Contact Microsoft Support
Because reinstalling and restoring accounts fails to fix this specific iOS bug, escalating the issue to Microsoft Support is necessary for a permanent patch.

Frequently Asked Questions
Why does Microsoft Authenticator freeze after I scan my Face ID on my iPhone?
This is typically caused by a software glitch or compatibility issue between specific iOS versions (such as migrating to a new iPhone 15) and the Authenticator app, preventing the user interface from transitioning away from the unlock screen.
Will deleting and reinstalling the Authenticator app fix the freezing issue?
For this specific bug where the app freezes on the unlock screen, many users report that deleting the app, reinstalling it, and restoring accounts does not permanently resolve the issue.
How can I log into my account if the Authenticator app is completely frozen?
You can force close the app on your iPhone, attempt your login from a computer web browser, and approve the authentication request directly via the iOS push notification banner without manually opening the Authenticator app.
What is the most important step to take before trying to fix the Authenticator app?
Always ensure you have alternative authentication methods set up on your Microsoft account, such as an SMS phone number, a backup email address, or recovery codes, so you do not get permanently locked out of your account.
