What to do if…
an operating system update locks you out of your device

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Stop guessing passwords or passcodes, connect the device to power, and use the official recovery path for that device type. Avoid bypass tools and do not erase or reset the device until you have checked whether you can restore your data and sign back in to the account linked to the device.

Do not do these things

  • Do not keep trying random passwords, PINs, or passcodes. Repeated failed attempts may trigger a timed lockout or leave an erase-and-reset route as the remaining official option on some devices.
  • Do not use bypass apps, jailbreak or root tools, or paid online unlock services.
  • Do not factory reset, erase, or reinstall the operating system as a first move.
  • Do not give an unknown shop or online helper your Microsoft, Apple, or Google Account password.

What to do now

  1. Pause repeated login attempts.

    • If the device shows a timed lockout, wait until the stated time has elapsed.
    • Write down the exact message on the screen before taking another action.

  2. Check for an input problem.

    • On a computer, check Caps Lock, the keyboard language, and whether a key appears to be stuck.
    • Disconnect docks and unnecessary USB accessories.
    • On a Windows PC, if the sign-in screen offers Sign-in options, try the password option instead of a PIN or biometric option.

  3. Use the official recovery path for the device type.

    • Windows PC
      • Use Microsoft’s Windows Recovery Environment instructions.
      • If the problem began after the update, use Uninstall Updates.
      • If the PC also fails to start correctly, use Startup Repair.
      • If BitLocker asks for a recovery key, stop before resetting the PC. Note the recovery-key ID and retrieve the matching key from your Microsoft account or contact your work or school IT team.
    • Mac
      • If the login window offers a password-reset message, follow the onscreen reset steps.
      • If the account is locked, wait until the stated time has elapsed, restart the Mac, and try again without guessing repeatedly.
      • If that does not work, use Apple’s macOS Recovery password-reset instructions.
    • iPhone or iPad
      • If you changed the passcode within the last 72 hours and the screen offers Forgot Passcode?, follow Apple’s onscreen option to try the previous passcode before erasing the device.
      • If the screen shows [Device] Unavailable or Security Lockout, Apple’s reset routes erase local data and settings.
      • An on-device reset may be available when the device has a supported operating-system version, an active cellular or Wi-Fi connection, Find My was previously enabled, and you know the Apple Account password.
      • If the on-device option is not available, follow Apple’s computer-based reset instructions for the iPhone or iPad.
      • Before erasing, check that you know the Apple Account password and whether you expect to restore from a backup.
    • Android phone or tablet
      • Google’s official guidance says that a device you cannot unlock may need to be erased and set up again.
      • A remote erase through Find Hub is available only when the device has power, is connected to mobile data or Wi-Fi, is signed in to a Google Account, has Find Hub enabled, and is visible on Google Play.
      • If remote erase is not available, use the manufacturer’s official instructions for the specific device.
      • Before erasing, check that you know the Google Account password and whether your data was backed up.

  4. Contact work or school IT before destructive recovery steps.

    • If the device is managed by an employer or school, contact IT before resetting, reinstalling, or changing account details. IT may need to provide a recovery key or handle the recovery process.

  5. Use official manufacturer support if the matching recovery path does not work.

    • Use the support route for Microsoft, Apple, Google, or the device manufacturer rather than an unknown unlock service.

What can wait

  • You do not need to decide whether to replace the device or pay for a repair right now.
  • You do not need to reinstall the operating system until the least destructive recovery options have been checked.
  • You do not need to reorganize your accounts, change platforms, or attempt advanced command-line repairs today.

Important reassurance

Login trouble after an update does not automatically mean that your data is gone or that your account has been compromised. Pausing repeated attempts and using the official recovery path helps preserve your options before any erase or reset.

Scope note

These are first steps only. Later decisions about rollback, reinstalling, restoring from backup, data recovery, or device repair may need help from the manufacturer, your work or school IT team, or a qualified technician.

Important note

This is general information, not professional IT, cybersecurity, legal, financial, medical, or therapeutic advice. Recovery options depend on the device, operating-system version, encryption settings, account access, management policies, and backups.
