Hi Nalesh In first link http://www.nullskull.com/a/10475154/token-based-authentication-in-wcf-service.aspx string UserToken = string .Empty; //Method to get employee data public Employee GetEmpData() { //Validating user token if (IsValidateUser()) { Employee objEmployee = new Employee(); objEmployee.EmpID = 1; objEmployee.EmpName = James ; return objEmployee; } else { throw new FaultException( Invalid User token to access data. ); } } //Method to validate user public string UserLogin( string userName string password) { //Validating user with static values you can validate from database if (userName == user1 && password == 123 ) { //If user is validated then returning current session id as user token UserToken = OperationContext.Current.SessionId; // It's return null Value } else { UserToken =  ; } return UserToken; } //Method to validate user with token public bool IsValidateUser() { //Getting the user token from client request if (OperationContext.Current.IncomingMessageHeaders.FindHeader( TokenHeader  TokenNameSpace ) == -1) { return false ; } string userIdentityToken = Convert.ToString(OperationContext.Current.IncomingMessageHeaders.GetHeader string >( TokenHeader  TokenNameSpace )); //Authenticating user with token if it is validated then returning employee data if (userIdentityToken == UserToken) { return true ; } else { return false ; } } And second article https://www.codeproject.com/Articles/1084143/Authentication-Token-Service-for-WCF-Services-Part using System.Security.Authentication; using WcfSimpleTokenExample.Interfaces; using WcfSimpleTokenExample.Model; namespace WcfSimpleTokenExample.Business { public class CodeExampleTokenBuilder : ITokenBuilder { internal static string StaticToken = {B709CE08-D2DE-4201-962B-3BBAC74C5952} ; // here I don't want fixed value; public string Build(Credentials creds) { if ( new CodeExampleCredentialsValidator().IsValid(creds)) return StaticToken; throw new AuthenticationException(); } } } Sir If you have any other idea plz share.
