Abstract
A computer-implemented method includes: receiving, by an authentication device, from a client device and via a network device, a plurality of passcode packets as part of a request to be authenticated by the authentication device; recording, by the authentication device, a sequence of port identifiers corresponding to respective ports of the network device via which the plurality of passcode packets are received; and authenticating, by the authentication device, the client device based on the sequence of port identifiers.
