New library (Phauxth) and status of Openmaize
First of all, I plan to continue maintaining Openmaize as long as people are still using it, but I have also started work on a library called Phauxth, which is designed with Phoenix 1.3 in mind and is also a lot more extensible.
If you are using Phoenix 1.3, take a look at Phauxth.
Authentication library for Plug-based applications in Elixir
Openmaize is a collection of functions, built on top of Plug, which can be used to authenticate users.
It should work with any application that uses Plug, but it has only been tested with the Phoenix Web Framework.
See the wiki for more information about Openmaize.
