I'm working on projects that use both .NET Framework and .NET Core using ID Server 3/4 respectfully (and of course separately) and I have become aware of the Implicit flow and how it works for Javascript clients. I do notice that it uses cookies and I think that is why a lot of redirects are happening, etc.
But in hindsight, it made me wonder if that would have a previous project better if we had known about Implicit flow then but without the use of cookies and just relying on session storage. Would that have been possible?
