I host a number of services for me and close friends and family, and I limit the access by manually creating accounts for them. I could enable OAuth via 3rd party service, but that would mean I'll have to pay much more attention to setup of ACLs, as these users will have a new account created for them with a link to their Github account. Besides, I want to stay more or less independent from 3rd party services, particularly I'm bothered by the need to explicitly register an OAuth client. AP has a much better flow in that regard, services can interoperate without a given permission to do so.
