Set up Pow

Be sure that you have installed PowAssent in mix.exs first.

Install the necessary files:

mix pow.install

Add the following to config/config.ex:

config :my_app, :pow,
  user: MyApp.Users.User,
  repo: MyApp.Repo

Set up WEB_PATH/endpoint.ex to enable session based authentication (Pow.Plug.Session is added after Plug.Session):

defmodule MyAppWeb.Endpoint do
  use Phoenix.Endpoint, otp_app: :my_app

  # ...

  plug Plug.Session,
    store: :cookie,
    key: "_my_app_key",
    signing_salt: "secret"

  plug Pow.Plug.Session, otp_app: :my_app

  # ...
end

Add Pow routes to WEB_PATH/router.ex:

defmodule MyAppWeb.Router do
  use MyAppWeb, :router
  use Pow.Phoenix.Router

  # ...

  pipeline :protected do
    plug Pow.Plug.RequireAuthenticated,
      error_handler: Pow.Phoenix.PlugErrorHandler
  end

  scope "/" do
    pipe_through :browser

    pow_routes()
  end

  # ...

  scope "/", MyAppWeb do
    pipe_through [:browser, :protected]

    # Protected routes ...
  end
end

Run mix ecto.setup and you can now visit http://localhost:4000/registration/new to create a new user.
