How to add claims in ASP.NET Identity

Viewed 95780

I am trying to find a document or example of how you would add custom claims to the user identity in MVC 5 using ASP.NET Identity. The example should show where to insert the claims in the OWIN security pipeline and how to persist them in a cookie using forms authentication.

Perhaps the following article can help:

var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, "Brock"));
claims.Add(new Claim(ClaimTypes.Email, "brockallen@gmail.com"));
var id = new ClaimsIdentity(claims,DefaultAuthenticationTypes.ApplicationCookie);

var ctx = Request.GetOwinContext();
var authenticationManager = ctx.Authentication;
authenticationManager.SignIn(id);

If you want to add custom claims at the time of registration then this code will work:

            var user = new ApplicationUser
            {
                UserName = model.UserName,
                Email = model.Email
            };
            var result = await UserManager.CreateAsync(user, model.Password);
            // Associate the role with the new user 
            await UserManager.AddToRoleAsync(user.Id, model.UserRole);
            // Create customized claim 
            await UserManager.AddClaimAsync(user.Id, new Claim("newCustomClaim", "claimValue"));
            if (result.Succeeded)
            {...etc

you can do the following in WEB API C #

var identity = new ClaimsIdentity(context.Options.AuthenticationType);          
        foreach(var Rol in roles)
        {
            identity.AddClaim(new Claim(ClaimTypes.Role, Rol));
        }
        identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
        identity.AddClaim(new Claim(ClaimTypes.Email, user.Correo));
        identity.AddClaim(new Claim(ClaimTypes.MobilePhone, user.Celular));
        identity.AddClaim(new Claim("FullName", user.FullName));
        identity.AddClaim(new Claim("Empresa", user.Empresa));
        identity.AddClaim(new Claim("ConnectionStringsName", user.ConnectionStringsName));
