Hi. There's nothing out of the box for API authentication. But I set up authentication in less than an hour for my app yesterday. You really want to learn how Plug works, and doing that opens up so many possibilities. I'm frustrated that there are so many things missing right now, because I'm used to Rails where everything exists right now. But I'm finding that having to do these things myself helps me really learn how Elixir works and it's opening up a lot of possibilities.
