Using Mobile Device Management (MDM) software, such as Intune ( Wi-Fi/ Wired).Computer Configuration > Policies > Windows Settings > Security Settings.Configuring the Wired Network (IEEE 802.3) Policies and Wireless Network (IEEE 802.11) Policies extensions in Group Policy.You can access the EAP properties for 802.1X authenticated wired and wireless access in the following ways: The following table lists some common EAP methods and their IANA assigned method Type numbers. Windows supports EAP-TLS and EAP-MSCHAP v2 as inner methods. The client support enables interoperation with commonly deployed RADIUS servers that support TEAP. In Windows Server 2022, the inclusion of TEAP only provides support for the client-side - Windows 10, version 2004 (build 19041). Supports EAP chaining - authenticating the machine and user within one authentication session. Tunnel EAP (TEAP): Described by RFC 7170, tunneled EAP method that establishes a secure TLS tunnel and executes other EAP methods inside that tunnel. As part of the plan, the customer commonly receives a wireless profile that is preconfigured for SIM authentication. The client support enables interoperation with commonly deployed RADIUS servers that support EAP-TTLS.ĮAP-Subscriber Identity Module (EAP-SIM), EAP-Authentication and Key Agreement (EAP-AKA), and EAP-AKA Prime (EAP-AKA'): Described by various RFCs, enables authentication by using SIM cards, and is implemented when a customer purchases a wireless broadband service plan from a mobile network operator. NPS doesn't support EAP-TTLS at this time. In Windows Server 2012, the inclusion of EAP-TTLS only provides support on the client-side (in Windows 8). This inner method can be either an EAP protocol, such as EAP-MSCHAP v2, or a non-EAP protocol, such as Password Authentication Protocol (PAP). Windows supports EAP-TLS and EAP-MSCHAP v2 as inner methods.ĮAP-Tunneled Transport Layer Security (EAP-TTLS): Described by RFC 5281, encapsulates a TLS session that performs mutual authentication using another inner authentication mechanism. The TLS tunnel secures the inner EAP method, which could be unprotected otherwise. Protected EAP (PEAP): Microsoft-defined EAP method that encapsulates EAP within a TLS tunnel. Windows 11 Enterprise, version 22H2 (build 22621) enables Windows Defender Credential Guard which may cause issues with MSCHAPv2-based connections. MSCHAPv2-based connections are subject to similar attacks as for NTLMv1. EAP-TLS can be deployed as an inner method for another EAP method or as a standalone EAP method. Appears as Smart Card or other Certificate (EAP-TLS) in Windows. This article contains configuration information specific to the following authentication methods in EAP.ĮAP-Transport Layer Security (EAP-TLS): Standards-based EAP method that uses TLS with certificates for mutual authentication. Methods that are set up as inner methods have the same configuration settings as they would when used as an outer method. ![]() Authentication methodsĮAP authentication methods that are used within tunneled EAP methods are commonly known as inner methods or EAP types. ![]() ![]() The EAP framework is originally defined by RFC 3748 and extended by various other RFCs and standards. EAP isn't a specific authentication method like MS-CHAP v2, but rather a framework that enables networking vendors to develop and install new authentication methods, known as EAP methods, on the access client and authentication server. Examples of these technologies include wireless access using IEEE 802.1X, wired access using IEEE 802.1X, and Point-to-Point Protocol (PPP) connections like Virtual Private Networking (VPN). The Extensible Authentication Protocol (EAP) is an authentication framework that allows for the use of different authentication methods for secure network access technologies. Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows 11, Windows 10, Windows 8.1
