Ionic authentication for login with angularjs

Question

As ionic uses angularjs, for login system there isn't any browser to save cookie or session in order to authenticate for each part of application. One way is protecting by using this in app.js:

$urlRouterProvider.otherwise('/login');

Because any one doesn't access to other links into application. When returned answer from server (mysql database) is true , we can use this:

$state.go('app.main');

Is this a good idea? Or any other ways?

Answer 1

Since ionic essentially calls to a back end api, you can implement any standard api authentication mechanism.

The most common was would be have a toke based authentication, High level workflow can be as follows

1 - ionic app calls a backend server end point and get a token (by passing some kind of an encrypted key)

2 - Back end server generates a token (ideal for a given time period) and sends back to the ionic app.

3 - There after, in every request ionic sends the token. (ideally in the request header)

To save the token temporary , you can use a simple storage solutions like ng-storage or sqlite
