Just add a PasswordBox to your XAML like so:

<PasswordBox x:Name="MyPasswordBox" KeyDown="MyPasswordBox_KeyDown" />

And then use the KeyDown event to remove all key presses that are not from 0 to 9, like so:

private void MyPasswordBox_KeyDown(object sender, KeyEventArgs e)
{
    e.Handled = (e.Key < Key.D0 || e.Key > Key.D9);
}
