Sign in with your password, then reset the forgotten PIN from Settings → Accounts → Sign-in options → PIN (Windows Hello) → I forgot my PIN.^1^
Reset the PIN
- On the Windows 11 sign-in screen, select Sign-in options.
- Select the password icon, then enter your Microsoft-account or local-account password.
- After reaching the desktop, open Start → Settings.
- Select Accounts → Sign-in options.
- Expand PIN (Windows Hello).
- Select I forgot my PIN.
- Follow the identity-verification prompts and create a new PIN.
Do not select Change PIN because that path requires the old PIN.
Reset it directly from the sign-in screen
If I forgot my PIN appears below the PIN box, select it and follow the prompts. This option is available for Microsoft accounts, but not local accounts.
For a local account, select Sign-in options → Enter your password, sign in, and reset the PIN through Settings using the steps above.^1^
The Windows Hello PIN is device-specific and is separate from your Microsoft-account password.
