You may have an app in which users are not permitted to sign up. Pow makes it easy to disable registration by removing the registration routes.
First you should follow the Modify templates section in README.
templates/pow/session/new.html.eex and remove the
Routes.pow_registration_path/2 link. Delete the
pow_session_routes() in your router module.
Add the following routes below to enable account updates and deletion:
scope "/", Pow.Phoenix, as: "pow" do pipe_through [:browser, :protected] resources "/registration", RegistrationController, singleton: true, only: [:edit, :update, :delete] end
