Dumb accounts-ui q: turn off email/pw signup, want twitter only

This is a totally dumb question, but at some point accounts-ui updated and started including username/password on my login page, even though I only want twitter login, for now. I don’t have the accounts-password package added, only accounts-twitter. Is there any easy fix? I’d prefer not to have pull apart accounts-ui and write my own login stuff, if I can avoid it. Thanks!
