We have been delivering developer training on the Microsoft Identity platform around the world. We finally managed to hit the studio and get some of these recorded. One of the big changes we made over time is to steer away from protocol details more towards concepts and APIs. It’s like why explain how NTFS works while you only want to write a file to disk with an API.
The entire series from me and my colleage Kyle Marsh are worthwhile watching. If you don’t have time at least watch the overview (1st video) and how to add authentication to your applications. It explains the concepts of tokens very well.
