How to change your PIN when you’re already signed in to your device?
To change your PIN when you're already signed in:
Make sure you're connected to the internet, so the change syncs to your Microsoft account.
Select Start > Settings > Accounts > Sign-in options.
Select PIN (Windows Hello) > Change PIN and then follow the instructions. You will need to know and enter your old PIN in order to change to a new one.
The PIN you use to access your device is different from your Microsoft account password.
