All banks I had an account at required verification for any payment order, including the direct debit. Some time ago (before widespread internet banking), you could issue an order that would be verified just against the details you mention _plus your signature_. I hope it's not possible anymore. At least my current bank lets you authorize direct debit in internet banking app. Anything you do in person requires either logging-in to the internet banking account at the branch or presenting an ID.
