I gotta secret for you. Authentication doesn't have to be hard to do right. Also, it doesn't need to be different for every backend or frontend framework you choose.
authonice is a platform/language/framework agnostic ecosystem for web-app authentication, with lots of inspiration from satellizer.
It's designed to work with lots of backend languages, auth services, & frontend frameworks. It's goal is to make you super-happy because your sites are safe, easy to setup & maintain, and stylishly locked-down in your language/frameworks of choice.
If we don't have a module for the frontend-framework/backend-language/auth-service you want to support, ask us or contribute!
