Can't Log In, New Installation

[Heaven Hodges]

I'm a new OpenBSD user. I've installed it as a guest OS in gnome-boxes 
(host OS is Debian Stretch). I chose to not create a user account, but I 
did input a password. When OpenBSD starts up, I'm presented with a login 
prompt. I have no idea what the login is. How can I log in or bypass the 
login prompt?
