When you are creating your new Login Tab from the MainWindow you can pass the whole MainWindow control (this) as a parameter to the Login tab.

From there you will be able to make calls on item inside the MainWindow from your Login Tab.

tabPage1.Enabled = false; // this disables the controls on it
tabPage1.Visible = false; // this hides the controls on it.

In the code below is taken from two separate Windows, the first one is called MainWindow and it has a button which opens a new window which I've called Window1.

MainWindow Code:

private void ButtonNewPage_Click(object sender, RoutedEventArgs e)
    {
        Window1 newWindow = new Window1(this);
        this.Hide();
        newWindow.Show();
    }

Window1 code, notice in the Window1 Constructor it takes a parameter of type MainWindow:

public partial class Window1 : Window
{
    private MainWindow parent;

    public Window1(MainWindow parent)
    {
        InitializeComponent();
        this.parent = parent;
    }

    private void ButtonOldPage_Click(object sender, RoutedEventArgs e)
    {
        this.Hide();
        parent.Show();
    }
}
