ASP.net Identity admin reset user password

I have an application which uses ASP.net Identity as for its user authentication.

I do not wish for users to reset their own password (for reasons which are not relevant here), so I have developed the following back end system to allow system administrators to reset the users password.

I have the following implementation:

Password Reset View:

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>ResetPasswordViewModel</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        @Html.HiddenFor(model => model.Id)

        <div class="form-group">
            @Html.LabelFor(model => model.NewPassword, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.NewPassword, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.NewPassword, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.ConfirmPassword, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.ConfirmPassword, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.ConfirmPassword, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Reset Password" class="btn btn-default" />
            </div>
        </div>
    </div>
}

AccountAdmin Controller

    // GET: /AccountAdmin/ResetPassword
    public ActionResult ResetPassword(string id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        ResetPasswordViewModel model = new ResetPasswordViewModel() { Id = id };
        return View(model);
    }

    //
    // POST: /AccountAdmin/ResetPassword
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult ResetPassword(ResetPasswordViewModel model)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        var removePassword = UserManager.RemovePassword(model.Id);
        if (removePassword.Succeeded)
        {
            //Removed Password Success
            var AddPassword = UserManager.AddPassword(model.Id, model.NewPassword);
            if (AddPassword.Succeeded)
            {
                return View("PasswordResetConfirm");
            }
        }

        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }

ResetPassword View Model

public class ResetPasswordViewModel
{
    public string Id { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "New password")]
    public string NewPassword { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm new password")]
    [Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }
}
