Your iCloud password may indeed be different than your Apple Password, but only you would know. Having said that, you can go to the iCloud website and then select forgot password to go through the process of resetting it.
Re: Is my I loud password different than my Apple password?
My iTunes Apple ID and my iCloud Apple ID are the same. But my wife and I share the ITunes Apple ID, so she has to have a different iCloud ID than mine. So her's are different.
