ok, very strange, as the password ***** ***** we are only left with the option to reset the PC
This will remove all your data and return the computer to new, but this you cannot avoid, its the whole point of the password.
To do this, on the sign in screen, hold SHIFT and with it held, click on the power icon and click restart.
Keep shift held until it has restarted, and your at a menu.
Then choose troubleshoot, then reset my pc.
Choose the option to remove your files, then let this complete and the computer is returned to as new and you can set it up again.
Let me know how you go please
