Install-Package Google-Authenticator-netcore -Version 1.1.0

    class Program
    {
        static void Main(string[] args)
        {
            TwoFactorAuthenticator tfa = new TwoFactorAuthenticator();

            string qrCodeImageUrl = setupInfo.QrCodeSetupImageUrl; //  在浏览器中打开该二维码 用手机上装好的谷歌身份验证器扫码(右下角-扫描条形码)
            string manualEntrySetupCode = setupInfo.ManualEntryKey; // 据说有的手机扫不了码, 则需要在谷歌身份验证器中手动输入该秘钥(也是右下角-输入提供的秘钥  账号名随意填,只是个名字  选择基于时间)

            string user_input = Console.ReadLine(); //模拟用户输入验证码
            TwoFactorAuthenticator tfa1 = new TwoFactorAuthenticator();
            bool isCorrectPIN = tfa.ValidateTwoFactorPIN("mysecretkey", user_input,TimeSpan.FromMinutes(1));//校验,  TimeSpan.FromMinutes(1) 目的是为了防止服务器时间和手机时间有差异,上下一分钟时间内的验证码也是允许的,默认5分钟
            if (isCorrectPIN == true)
            {
