It looks like there are three options for the sever side of ember-simple-auth
- simple-auth-oauth2 provides an OAuth 2.0 authenticator
- simple-auth-devise provides an authenticator compatible with the popular Ruby on Rails authentication plugin devise
- simple-auth-torii provides an authenticator that wraps the torii library
My server is NodeJS so item 2 is out.
What the is difference or pros/cons of items 1 and 3?
