Port-based authentication is a form of "security by obscurity" wherein any device connecting to a system via the selected port is assumed to have authority to access said system. This can be dangerous if the port is randomly guessed, or shared by an someone who has previously been authorized. In this way, port-based authentication is equivalent to using a weak (or even default) password.
