Push notifications android error

Hi I want to include push notifications in my app. I followed all steps: Creating a Google API project, Enabling the GCM Service, Obtaining an API Key, and putting Google API key and GCM sender ID in android push notification section under development and settings on titanium website. I run the code below in app.s and test on real device. I get the following error: 'error: invalid email/username and password'.

What is my solution?

Titanium.UI.setBackgroundColor('#000');
 
var win = Ti.UI.createWindow({
    backgroundColor:'#ccc',
    title:'Android Cloud Push Notification'
});
 
 
var CloudPush = require('ti.cloudpush');
        CloudPush.debug = true;
        CloudPush.enabled = true;
        CloudPush.showTrayNotificationsWhenFocused = true;
        CloudPush.focusAppOnPush = false;
 
    var deviceToken;
 
    var Cloud = require('ti.cloud');
    Cloud.debug = true;
 
 
var submit = Ti.UI.createButton({
    title : 'Register For Push Notification',
    color:'#000',
    height : 53,
    width : 200,
    top : 100,
});
 
win.add(submit);
 
submit.addEventListener('click', function(e) {
        CloudPush.retrieveDeviceToken({
                success: function deviceTokenSuccess(e) {
                    alert('Device Token: ' + e.deviceToken);
                    deviceToken = e.deviceToken;
                    loginDefault();
                },
                error: function deviceTokenError(e) {
                    alert('Failed to register for push! ' + e.error);
                }
        });
    });
 
 
   function loginDefault(e){
    //Create a Default User in Cloud Console, and login
    Cloud.Users.login({
        login: 'push123',
        password: 'push123'
    }, function (e) {
        if (e.success) {
            alert("login success");
            defaultSubscribe();
        } else {
            alert('Error: ' +((e.error && e.message) || JSON.stringify(e)));
            }
        });
    }
 
    function defaultSubscribe(){
                Cloud.PushNotifications.subscribe({
                    channel: 'alert',
                    device_token: deviceToken,
                    type: 'android'
                }, function (e){
                    if (e.success) {
                       alert('Subscribed for Push Notification!');
                    }else{
                        alert('Error:' +((e.error && e.message) || JSON.stringify(e)));
                    }
                });
    }
 
    CloudPush.addEventListener('callback', function (evt) {
    //alert(evt);
    //alert(evt.payload);
});
 
CloudPush.addEventListener('trayClickLaunchedApp', function (evt) {
    Ti.API.info('Tray Click Launched App (app was not running)');
    //alert('Tray Click Launched App (app was not running');
});
 
CloudPush.addEventListener('trayClickFocusedApp', function (evt) {
    Ti.API.info('Tray Click Focused App (app was already running)');
    //alert('Tray Click Focused App (app was already running)');
});
 
 
win.open();
