Log In screen

Every time I restart my computer, I get this box that comes up and then I have to log in to my account. It's just me on this computer, I have no password set. before I didn't have to do it, but with some issues apple support had me make another account and even though I have deleted the other account, I still get that box come up. I want to have my computer turn on without me having to do this step. How?
