XNA is bootstrapped in the Program.cs. Just add code in your winforms when the client is authenticated that starts the XNA game like in the Program.cs.

See http://www.codeproject.com/Questions/303672/XNA-And-Windows-forms

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        button1.Text = "Start!";
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Thread theThread = new Thread(StartGame);
        theThread.Start();
    }
    public void StartGame()
    {
        Game1 game = new Game1();
        game.Run();
    }
}
