Firebase Authentication

Authentication State Persistence

Issue #35 deals with persistence across multiple devices or tabs. There are three settings for persistence in firebase:

• firebase.auth.Auth.Persistence.LOCAL: state is persisted even when tab is closed; explicit sign out needed. Signing in anywhere is detected and synchronized.
• firebase.auth.Auth.Persistence.SESSION: state is cleared when tab is closed. Each tab cannot see the state of the other tab.
• firebase.auth.Auth.Persistence.NONE: state is cleared when tab is refreshed To set,
• use firebase.auth().setPersistence(firebase.auth.Auth.Persistence.SESSION).
• "only sets on the specified Auth instance for the currently saved Auth session and apply this type of persistence for future sign-in requests"
• returns "a promise that will resolve once the state finishes copying from one type of storage to the other"
• default is local
