This has to be one of the funniest exchanges I've ever seen!
Ok, ok. I've stopped laughing.
To be serious for a moment. Why would he assume you aren't trying to scam some btc out of an account? You couldn't give the password even with hints and didn't know when last withdrawal and for how much.
Password reset can be done via email, for example. No one asks for the password itself.
Just like every normal website works!!
Or he could send the money to the last address.
