ASP.NET Core 2.1错误？两因素验证（2FA）

Question

启用2FA后，它仍然显示设置按钮吗？ （ASP.NET Core 2.1）

请参见下面的屏幕截图

代码（标准代码未修改）

@page
@model TwoFactorAuthenticationModel
@{
    Layout = "_Layout.cshtml";
    ViewData["Title"] = "Two-factor authentication (2FA)";
}

@Html.Partial("_StatusMessage", Model.StatusMessage)
<h4>@ViewData["Title"]</h4>
@if (Model.Is2faEnabled)
{
    if (Model.RecoveryCodesLeft == 0)
    {
        <div class="alert alert-danger">
            <strong>You have no recovery codes left.</strong>
            <p>You must <a asp-page="./GenerateRecoveryCodes">generate a new set of recovery codes</a> before you can log in with a recovery code.</p>
        </div>
    }
    else if (Model.RecoveryCodesLeft == 1)
    {
        <div class="alert alert-danger">
            <strong>You have 1 recovery code left.</strong>
            <p>You can <a asp-page="./GenerateRecoveryCodes">generate a new set of recovery codes</a>.</p>
        </div>
    }
    else if (Model.RecoveryCodesLeft <= 3)
    {
        <div class="alert alert-warning">
            <strong>You have @Model.RecoveryCodesLeft recovery codes left.</strong>
            <p>You should <a asp-page="./GenerateRecoveryCodes">generate a new set of recovery codes</a>.</p>
        </div>
    }

    if (Model.IsMachineRemembered)
    {

    <a asp-page="./GenerateRecoveryCodes" class="btn btn-default">Reset recovery codes</a>
