AWS finally added the ability to swap between a few accounts [1]. There’s an arbitrary limit of 5 so it’s really bad if, say, you work for an enterprise and have lots of accounts or, say, you work for a smaller business following the AWS Well-Architected Framework and isolate things. Containers still win.
I am not sure… a microsoft login normally seems to jump across tens of different domains and my firefox containers get confused and it often fails if the stars are not well aligned.
