If someone asks for your password you can be sure that they want it for the wrong reasons. No Habbo has the power to give out free Habbo Credits (not even Hobbas).

These scamster Habbos use your password to sign into Habbo Hotel as you. Then they can steal your furni, spend your Habbo Credits and even pretend to be you when they talk to your friends. They might even change your Habbo password, so you won't be able to get your Habbo back.
