The following credential types can be used:

Whether there should be a server validation notificationįor a UWP VPN plug-in, the app vendor controls the authentication method to be used.

Trusted root certificate for server certificate.

Server validation: in TTLS, the server must be validated.

This process, termed "cryptobinding", is used to protect the PEAP negotiation against "Man in the Middle" attacks. This reduces resource requirements for both client and server, and minimizes the number of times that users are prompted for credentials.Ĭryptobinding: By deriving and exchanging values from the PEAP phase 1 key material ( Tunnel Key) and from the PEAP phase 2 inner EAP method key material ( Inner Session Key), it is possible to prove that the two authentications terminate at the same two entities (PEAP peer and PEAP server).

Inner method - the outer method creates a secure tunnel inside while the inner method is used to complete the authentication:įast Reconnect: reduces the delay between an authentication request by a client and the response by the Network Policy Server (NPS) or other Remote Authentication Dial-in User Service (RADIUS) server. Server validation - with PEAP, server validation can be toggled on or off: Protected Extensible Authentication Protocol (PEAP): Notification - specify if the user should get a notification asking whether to trust the server or not.Server certificate - trusted root certificate to validate the server.Server name - specify the server to validate.Server validation - with TLS, server validation can be toggled on or off: Filtering can be Issuer-based or extended key usage (EKU)-based.Certificate filtering can be enabled to search for a particular certificate to use to authenticate with.Certificate with keys in Trusted Platform Module (TPM) KSP.Certificate with keys in the software Key Storage Provider (KSP).Supports the following types of certificate authentication: Winlogon credentials - can specify authentication with computer sign-in credentials.Windows supports a number of EAP authentication methods.ĮAP-Microsoft Challenge Handshake Authentication Protocol version 2 (EAP-MSCHAPv2): You can only configure EAP-based authentication if you select a built-in VPN type (IKEv2, L2TP, PPTP or Automatic).

In addition to older and less-secure password-based authentication methods (which should be avoided), the built-in VPN solution uses Extensible Authentication Protocol (EAP) to provide secure authentication using both user name and password, and certificate-based methods.
