    [Display(Name = "Password")]

    //

    [AllowAnonymous]
    public ActionResult LogOn()
    {
        LogOnViewModel model = new LogOnViewModel();
 
        return View(model);
    }
 
    //
    // POST: /Account/LogOn
    [AllowAnonymous]
    [HttpPost]
    public ActionResult LogOn(LogOnViewModel model, string returnUrl)
    {
        if (this.ModelState.IsValid && Membership.ValidateUser(model.UserName, model.Password))
        {
            FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
            if (this.Url.IsLocalUrl(returnUrl))
            {
                return Redirect(returnUrl);
            }
            else
            {
                return RedirectToAction("Index", "Home");
            }
        }
 
        // If we got this far, something failed, redisplay form
        this.ModelState.AddModelError("", "Incorrect user name or password.");
        return View(model);
    }
 
    //
    // POST: /Account/LogOff
    [HttpPost]
    public ActionResult LogOff()
    {
        FormsAuthentication.SignOut();
 
        return RedirectToAction("Index", "Home");
    }
}

}
<!DOCTYPE html>

<body>
    <h2>@ViewBag.Title</h2>
    @using (Html.BeginForm(null, null, new { returnUrl = ViewBag.ReturnUrl }, FormMethod.Post))
    {

        @Html.ValidationSummary(true)<br />
        @Html.TextBoxFor(m => m.UserName, new { placeholder = Html.DisplayNameFor(m => m.UserName) })<br />
        @Html.PasswordFor(m => m.Password, new { placeholder = Html.DisplayNameFor(m => m.Password) })<br />
        @Html.CheckBoxFor(m => m.RememberMe)
        @Html.DisplayNameFor(m => m.RememberMe)<br />
        <button type="submit">Log On</button>
