  1. How do you know that?

  2. As far as I can tell, I’m passing the default for claims, which is %{}:

 conn
    |> put_flash(:info, "Welcome back!")
    |> Guardian.Plug.sign_in(Guardian, user)

put_flash() returns a conn, so I am calling:

Guardian.Plug.sign_in(conn, Guardian, user)

and based on the definition of sign_in():

sign_in(conn, impl, resource, claims \\ %{}, opts \\ [])

I’m actually calling:

Guardian.Plug.sign_in(conn, Guardian, user, %{}, [])
