Reset local account password for Windows 10, version 1803 and beyond

If you added security questions when you set up your local account for Windows 10, then you have at least version 1803 and you can answer security questions to sign back in.

After you've entered an incorrect password:

  1. Select the Reset password link on the sign-in screen. If you use a PIN instead, see PIN sign-in issues. If you're using a work device that's on a network, you may not see an option to reset your password or PIN. In that case, contact your administrator.
  2. Answer your security questions.
  3. Enter a new password.
  4. Sign in as usual with the new password.

Reset local account password for Windows 10, before version 1803

For versions of Windows 10 earlier than 1803, local account passwords can't be reset because there are no security questions. You can reset your device to choose a new password, however this option will permanently delete your data, programs, and settings. If you've backed up your files you'll be able to restore your deleted files. For more information, see Recovery options in Windows 10

To reset your device, which will delete data, programs, and settings:

  1. Press the Shift key while you select the Power  button > Restart in the lower-right corner of the screen. 
  2. On the Choose an option screen, select Troubleshoot > Reset this PC.
  3. Select Remove everything

You may need to reset your password. Here’s how:

  • Sign in to your Microsoft account using your current password. If you forgot your password, either select Forgot my password and follow the steps. Or, for deeper account sign-in issues, see How to reset your Microsoft account password.
  • Once you've signed in, select Security.
  • Select Password security.
  • Type your current password, then type a new password and type it again to verify.
  • Select Save.

Are you able to sign in?

You’ll need to fill out the online safety form.

If you see one of those messages, Windows will create a temporary profile and sign you in to that one.


First, use an external drive to save any work you’ve done since your last successful sign in. Any files you have created or changed while in the temporary profile will be lost when you sign off.

Restart your device in safe mode and sign in with your original profile. Check to see if your settings and files are restored.
