In my opinion, Apple users can unlock iPhone via iCloud if “Find My iPhone” is turned on. Just signing in to iCloud and select 'Erase iPhone'. But, all the data including the passcodes will all be removed. If you have turn off “Find My iPhone” and forgot the iCloud password, you can use a 3rd-party iPhone Unlock tool such as UkeySoft iPhone Unlocker, it can help you easily to unlock your disabled iPhone without passcode in one click.
