Passwordless sign in not working 20H2

My wife and I are the only users of our home pc and would like to be able to do away with passwords. I did not have the "netplwiz box" so I followed the directions (altering the registry) to change the dword from 2 to 0. The box is now back but does not seem to be working - I can only move the cursor when the box is checked (seems counter-intuitive) and even though I make the change to one user or the other, both of us must still enter a password to sign in. Any help will be appreciated.

P.S. I'm a retired computer programmer and should be able to get this to work...

I say go back to the registry and undo what you did there.
Then go to settings--Accounts--- sign in option and click on Password.
After that you should be able to use netplwiz to make the booting automatic
