Troubleshooting guide
How to fix the problem
Separate your account password and Windows Hello PIN. Change your local account password in Settings > Accounts > Sign-in options > Password, if available. Change your Microsoft account password on the official account.microsoft.com security page. The PIN is changed in a separate login option and is not a common account password.
If the problem persists
First, determine whether you're changing your local account password, your Microsoft account password, or just your Windows Hello PIN. If you forget your password, use the official recovery for that account.
