Technologies for providing multiple device authentication in a heterogeneous network include a gateway node. The gateway node includes a network communicator to receive a request from a terminal node to authenticate a user of a set of heterogeneous nodes connected to the gateway node and broadcast a credential request to the nodes. Additionally, the gateway node includes a response combiner to combine responses from the set of nodes to generate a combined authentication message. The network communicator is further to send the combined authentication message to the terminal node for authentication. Other embodiments are described and claimed.
