For most website and apps, the default Hosted Login project is the easiest way to offload user management pages to Stormpath. It’s production-ready, built on best-practices and easy to customize. However, you can absolutely build your own Hosted Login pages. There is no requirement for you to use ID Site, Stormpath's hosted login solution, however it does save you a lot of time and effort. You can learn more about ID Site in our Docs and how customizable it is. However, if you need even more flexibility and customized workflows, building your own might be the best option for you.
