Accessing data stored in cookies?

Question

In login, I store user information logged in to a cookie (name, password, etc...)

How do I access this cookie and redeem information from it?

For example, I want the name of the logged in user to appear in the top bar, by my logic I would have to find the name that is already stored in the file and play it in a @Viewbag determined in the controller, is this way of thinking correct? And what is the most aesthetic and correct way of doing this action?

Follow the example of when you authenticate:

[HttpPost]
    public ActionResult Login(Login form, string retornarurl)
    {
        var usr = db.Usuario.FirstOrDefault(u => u.nome == form.nome);

        if (usr == null || !usr.CheckPassword(form.passwordHash))
            ModelState.AddModelError("nome", "Usuário ou senha estão incorretos ou não existe");

        if (!ModelState.IsValid)
            return View(form);

        FormsAuthentication.SetAuthCookie(usr.nome, true);

        return RedirectToAction("Index", "Admin" );

    }

You use the old way, which was used in Web Forms. It can be done this way:

HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);

string cookiePath = ticket.CookiePath;
DateTime expiration = ticket.Expiration;
bool expired = ticket.Expired;
bool isPersistent = ticket.IsPersistent;
DateTime issueDate = ticket.IssueDate;
string name = ticket.Name;
string userData = ticket.UserData;
string version = ticket.Version;

I recommend you take a look at ASP.NET Identity, that performs more interesting user management and the cycles of registration, login and registration of external logins.
