Windows 10: How to windows 10 lost login password

I used to login in my windows 10 desktop computer using PIN. Recently, the computer reported unexpected error occurs the PIN is lost, and required to login using password which I do not remember. How can I recover it.

Password issue

After going through the steps to make a new password, after a week or two, my login credentials are no longer valid. I'm forced to make a new password all over again. It seems to happen if I don't login in a certain period of time. Does our passwords expire???

 

No login password craziness

Brink, that was the missing step. What threw me off was in netplwiz, where it asks about password for my MS account, the user name was not the same as my MS account name. Once I entered the password (twice) I can now login without entering a password. In fact the name that was listed was not the MS account name, but a folder name. The folder is the one that shows when you click on C:\Users.
Thanks for the help.

 

Lost My Administrator Password

To which "this" are you referring?
- If you are following the tutorial Bree suggested in the very first reply to your question then what you need to do at each step is explained in detail. So which step are you at?
- If you are following a different procedure then state what it is and which step you are at. If, for example, you are trying to manually enable the Built-In Admin as suggested in post #11 then that account has no password.
