I think we’re long past the point where “hacking” in this sense has any sort of connotation of skill (and that is probably for the best). “Hack” is just a more colloquial synonym for “compromise”.
People seem to have adopted the term "hacking" to imply any and all unwanted access to a device or system. As far as I recall it meant that a device or system was modified in a way that was not originally intended. Logging in with the password is an intended use-case of the device, therefore not hacking in my opinion.
Years ago a teenager was arrested for "hacking" because he just Google'd the answers to Sarah Palin's security questions to gain access to her Yahoo account.
