Passwords

Options

I use TV Free internally in my home office between a Win 7 laptop and a Win 10 PC because I have S/Ware on the Win 7 that won't run on 10 and prefer using the 10. When I started using TV I managed to set up a four digit password which made life easier. It's now reverted to the random long password. How do I go back to simple password or even no password at all ? Thanks.
