I am trying to run some xConnect facet/identification code after a user logs in with Federated Auth. But it seems like all the Owin pipelines have no tracker available. And none of the Sitecore pipelines know you just logged in.
Any pipelines in Sitecore where you know you just logged in with a tracker available.
CreateTracker - user is not logged in yet StartTracker/StartTracking - Tracker is alive, but no way to tell which time is the first page post login. Since StartTracking runs on every page.
