Extensible Authentication Protocol Host
EAPHost is a Microsoft Windows Networking component that provides an Extensible Authentication Protocol (EAP) infrastructure for the authentication of "supplicant" protocol implementations such as 802.1X and Point-to-Point (PPP). It also allows for authentication with "authenticator" technologies such as the Microsoft network policy server (NPS). Unlike the previous IAS Server (RADIUS), NPS supports Network Access Protection (NAP).
The EAPHost APIs enable applications to authenticate using the EAPHost service, and provide a template for the development of conformant authentication methods for use with EAPHost.
Run-time requirementsThe EAPHost APIs are supported only in Windows Vista and later operating systems.
