"I have set a password as well as a PIN to log in to Windows 10. I usually choose to use the PIN instead of the password to sign in. Because I haven’t used my password for a long time, I have forgotten it, but I still remember the PIN. How can I change or reset my password? It is a local admin account."
Sorry for you forgot your password, but lucky for you remember the PIN, which means you still can sign in to Windows 10 with the PIN and makes it an easy task to change or reset your password. The methods depend on whether you are using a local account or a Microsoft account.
If you are using a local account and you have forgotten your password, log in to Windows 10 with your PIN, and then change your password with any of the following two methods. The two methods allow you to change the Windows 10 password without requiring you to enter your old password.
Step 2: Type net user <username> <password> and press Enter. Note: Replace the <username> with your user name, and replace the <password> with your new password.
Step 1: Open the Local Users and Groups.
Step 2: Click on the "Users" folder to show all users, right-click on the user whose password you’ve forgotten, and select "Set Password".
Step 3: Click Proceed, and then set a new password for the user.
If you are using a Microsoft account and forgot the password, but you still remember the PIN, you need to reset your password online from Microsoft website.
Step 1: sign in to Windows 10 with the PIN.
Step 2: Open the browser, go to https://account.live.com/password/reset, and follow the screen to reset your Microsoft account password.
If for some reason the methods above don’t work for you, sign in to Windows 10 with your PIN and then try to use the Windows Password Refixer to reset your password.
