Default Web Login Page - Session Authentication

I know domcfg.nsf is for customizing the web loging form $$LoginUserForm

My question is, if I do not setup domcfg.nsf, and I turn on session authentication, where is the default form coming from? I assume it’s still $$LoginUserForm, but where is it getting this to use if domcfg.nsf does not exist?

Thanks!
