In my case it would still backfire. I wouldn't know what the response would be if I _had_ given them the password. It would make me think the person hiring me was being manipulative and dishonest. And that is a best-case scenario.

Secondly, it would be setting the bar way too low. I don't appreciate being congratulated for not being an idiot. Someone congratulating me and actually being impressed of that fact makes me think less of that person.

A pretty bad start to a supposedly long relationship, if you ask me.
