I know this problem has probably been handled by everyone, so what are the Ember best practices for implementing login/authentication wrapped with security?
This brings me to another point, is the community sharing controls? If so, is there a site to browse user created controls? I would be happy to share any controls which might be useful for the community.
Restful API with a token-based authentication mechanism but cookie-based storage of some session hash works just as well. A good foundation that covers most needs is ember-simple-auth.
Do you have a specific question around authenticating?
