At my current company I am working on my first large-scale production backbone.js app and I couldn’t be happier. After using backbone.js for a few months I have caught the vision and I am becoming more and more proficient. But every once and a while I still run into problems I would consider basic, but I can’t seem to find much help on the interwebs. Authentication with backbone.js apps was one of those problems. So I am posting the solution I came up with in hopes it will benefit someone else, and hopefully will garner some feedback or potentially better ways to solve authentication with Backbone.js.
