This is a sample Ionic project that uses Auth0 for Authentication and Firebase for storing information. It's the basic tabs example from Ionic with the added authentication from Auth0 and Firebase as the backend.
This example uses Refresh Tokens so that you will see the Login page only the first time you create the app and then never again.
In order to run the project, you need to have node, ionic, cordova and ios-sim installed.
Once you have that, just clone the project and run the following:
npm installionic platform add iosionic build iosionic emulate ios
Enjoy your Ionic app now :).
