Since, you are storing Passwords using Isolated Storage, you can simply use this.

public MainPage()
{
    InitializeComponent();
    Loaded += MainPage_Loaded; 
}

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    if (IsolatedStorageSettings.ApplicationSettings.Contains("LoginPassword"))
    {
        // so, if login password has already registered, it will redirect to LoginPage
        NavigationService.Navigate(new Uri("/LoginPage.xaml", UriKind.Relative));
        //else it will be in MainPage where user can enter their password
    }
}

Don't forget to add this code in your 'LoginPage', this will restrict user not to back to 'MainPage' again;

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    while (NavigationService.CanGoBack)
    {
        NavigationService.RemoveBackEntry();
    }
}
