A couple years ago, after a long-winded process seeing it's inventor drop out of the process in frustration, Open ID Connect was poised to become the portable authentification/identity mechanism of choice for logging in using Fb's, Google's, and other provider's (Apple's/icloud's?) user base. I still don't fully understand what has happened to the few interworking initiatives that were created in the 2010s compared to the 2000s. I mean, using Fb and Google as identity provider has maybe its own set of issues, but the expectations we had towards tech were markedly different in that proprietary protocols were universally rejected.
