Want to know something really annoying? I bank with multiple banks. One institution uses access tokens. I can link them to my primary bank (the primary has a better "whole picture" view). But does my primary bank offer access tokens of their own? No. They understand the concept, but don't use it themselves.

Of course, I know why. Different teams. There's no cohesive vision to their IT work, same as every other enterprise out there.

EDIT: Cleaned up language. Removed some info I didn't really want here but really botched the posted version when I did.
