Store cookies in browser

ASP.NET

WebAPI

I have Asp.net web Application project with WebApi and individuals user Account.
I implemented Registration and login, and I used angularjs in front end.

Now, I need to store cookies in browser.

I'm confuse if authentication based on cookies store cookies in browser?

In my project I authenticate users based on token.

I do research but it confuse me and I did't find a clear guide to store cookies using Asp.Net Identity webApi.

What I have tried:

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password);

        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }
       /* 
   I tried the following but I get an error that Request doesn't exist

 var claims = new List<Claim>();
        claims.Add(new Claim(ClaimTypes.Name, context.UserName));
        var id = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);

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


                 */



        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        ClaimsIdentity cookiesIdentity = await user.GenerateUserIdentityAsync(userManager);

        AuthenticationProperties properties = CreateProperties(user.UserName);
        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        context.Validated(ticket);
        context.Request.Context.Authentication.SignIn(cookiesIdentity);
}

Please don't provide me with link to asp.Net Identity MVC, I want WebApi.
