## What it is
Ember Simple Auth is a lightweight library for implementing authentication and authorization in Ember.js applications. It maintains a client-side session with pluggable authenticators and session stores, supporting custom backends and external providers.

## Use cases
- add login and logout to an Ember.js app
- maintain a client-side session across tabs
- authenticate against an external OAuth provider like Facebook or GitHub
- authorize API requests with tokens
- store session state persistently in the browser

## When to choose
- you are building an Ember.js application that needs user authentication
- you want pluggable, extensible auth strategies with minimal app structure requirements
- you need session synchronization across multiple browser tabs

## When to avoid
- your app is not built with Ember.js
- you need server-side session management only
- you require IE11 support

## Facets
- artifact type: library
- maturity: active
- function: auth, authorization, middleware
- domain: web-development, frontend, security
- platform: browser
- tags: ember, ember-addon, session-management, authentication, javascript, nodejs, web-server
