A Google search lists quite a few fixes to change the login password - some appear to be more simple that others. I haven't tried any of them, but most of them seem to have worked for other users.
Finally - or perhaps rather as a first step - persist for a while with what you think the password might have been. Good luck - it appears to be do-able.
I assumed the OP knows the password but doesn’t want the chore of typing it in each time?
If Googles’s suggestions don’t work you could try creating a new user without a password and then deleting the user you have.
But watch out you don’t lose access to any files or apps associated with the old owner. Make sure the new user has access to them before deleting the old.
