I had the same experience at the apple store a few years ago, where they asked me for my password. They insisted they needed it to run "hardware checks." I think I ended up just wiping it before giving it to them.

I wasn't happy about it, so I complained to corporate. I got a voicemail a few days later from a very apologetic store manager, saying that they would review the policy (who knows if they did). Furthermore, they found issues with my logic board, and replaced it (out of warranty) for free. So that was nice. Still wouldn't ever turn in a computer for service without wiping it however.
