Hello Microsoft Support Team,

I am experiencing a recurring issue with Microsoft Authenticator on my Samsung Galaxy S23 Ultra.

App version: 6.2610.7075.

The application frequently freezes on the startup logo and displays the error "Authenticator isn't responding."

Sometimes the app opens normally and displays all my accounts and verification codes, but the problem returns the following day.

I have already tried:

  • Updating Microsoft Authenticator.
  • Force stopping the app and clearing its cache.
  • Restarting my phone.
  • Checking battery settings and automatic date/time.
  • Switching between Wi-Fi and mobile data.
  • Updating and reinstalling Android System WebView updates.

Unfortunately, the problem persists.

Please investigate this issue and provide a permanent solution compatible with the Samsung Galaxy S23 Ultra.

I especially need instructions to fix the problem without losing my saved authentication accounts, verification codes, or sign-in approval functionality.

Thank you for your assistance.

    Hello @Duong Huu Trung

    Since this is a user-to-user community forum, I can only provide guidance and troubleshooting suggestions based on my experience as a user and the information you have shared. 

    At the moment, I have not found any confirmed reports from either the Microsoft Community or Samsung Community indicating a known compatibility issue specifically between the Samsung Galaxy S23 Ultra and the Microsoft Authenticator app.

    As a troubleshooting step, please first make sure that you have an alternative MFA method configured as a backup, so you can still access your account if needed. Once this is confirmed, please try reinstalling the Microsoft Authenticator app and check whether the issue persists.

    If the issue continues, you can submit feedback directly through Microsoft Authenticator. Open the navigation menu in the upper-right corner, select Send feedback.
