Overwrite Pow Route

I think you just need to set as well a path in your router for the create action.

Here is how I did it:

# Registration route
  scope "/compte/inscription", Pow.Phoenix, as: "pow" do
    pipe_through :browser
    get "/", RegistrationController, :new
    post "/", RegistrationController, :create
  end

Just replace “/compte/inscription” by whatever you want to show up as registration url in the browser. That would be “/” in your case.
