    It’s such a product of “Ooh! Markup languages! What can we use a markup language to solve!” When authentication is just not a document or data stream that needs marked-up.

    The article rightly connects this to XML, which was indeed the hammer to everything’s nail at the time

    I think we aren’t done with this problem yet, though. OIDC makes a lot of assumptions in service to Google and others. And tailscale as mentioned, despite “holding the line,” already reveals the cracks when things like GitHub accounts have to be treated differently from others.

    What we are missing is a provider-independent way to do this. I should be able to create an account and log in just about anywhere using a backend I control. It can be done, but not with what we have today

      You can do that in principle. Most non enterprise tools don't support it because they don't merely want an IdP, they want an IdP doing anti-spam and reputation and outsourcing of account recovery and throttling of bulk user creation.

      If anyone could attest to who they are at any time we could just have user/pass without email and call it a day.
