Thanks.  My reading of the code of oauth2.el is that oauth2-compute-id
derives the id for plstore from auth-url, token-url, and scope.  It
seems to me that this will get confused with, say, two different
Office365 accounts that have the same auth-url, token-url, and scope.
Should the code use also additional information such as the user name?
(I do not know much about plstore.el used by oauth2.el.)
