Hi! You must have linked your Microsoft Account to Windows. When you do this, Windows asks you to set a PIN.
- You can use the PIN you created to unlock your computer, or you can use the same password as your email.
- Click on Sign-in options > Key icon for Password, and Number keypad icon for PIN.
If you want to remove your password, you must remove your account from Windows.
- Open Settings > Accounts > Your Info > Sign in to a Local Account > Leave the password field blank > Proceed.
- You can see in Sign-in options > Password > if you can remove the password.
