So we have an "internal" package that we install on all of our sites that lets us in to the sites using a shared password. We are implementing IBackOfficeUserPasswordChecker. On Umbraco 8 we also included a custom OwinStartup class and could set the web.config value on package installation. On here: it says to modify ConfigureServices() but I wondered if there was another way that would be more automatic (such as implementing IComposer). I don't mind modifying Startup.cs but was curious if we could implement something for automatic registering.
