V1 and V2 Identity and Access tokens with Azure Active Directory
This has caused me a ton of confusion and my customers keep getting confused as well. Azure Active Directory has been around for some time now. Some time ago we added a new endpoint (V2) which is more standards compliant and supports both AAD and MSA accounts and for example features like incremental consent. Still people get confused about our numbering scheme and I totally understand why. Let me try to explain a little bit how this all works.
