typically a service like this is set up for B2B, where you'd have an IT department managing an identity provider already
i could host my own openid provider and drive myself fully mad
i am the fucking weirdo that runs my own IdP and even i had the brief moment of lucidity necessary to understand that attaching my single-user network that bridges a world of computers to something that i myself run is an insane idea
"sign up with your identity provider" is a thing I would not write in a cyberpunk story because it would be too hamfisted
AND YET
okay, but, remember when you could use a LJ account for openid/oidc
