In aspects of enhanced network access-control credentials, a network access device includes a network interface for data communication with network-connected devices via a network. The network access device implements an access control manager that receives a network access request from a requesting device to access the network, where the network access request includes authentication credentials. The access control manager can then modify the network access request to generate a modified network access request, and initiate communication of the modified network access request to an authentication server that authenticates the requesting device to the network based on the modified network access request.
