See title.

Are you referring to the authentication protocol?

Yes. My apologies if there was any confusion. I have looked into it in the past and forgot about it. You jogged my memory ...

Hi SBS,

OpenID Connect is a profile of (i.e. a collection of conventions for using) OAuth2.0 to allow a third party identity provider to authenticate an identity wanting to enter an access controlled Web domain. OAuth2.0 was originally developed as an authorization protocol, to allow people to control access to Web resources, like their calendars or photos. OpenID Connect extends OAuth to authentication. Check out these links - OAuth2.0OpenID Connect - for more information.

Hope that helps.

I see causality in the fact that I don't have an Openid

Hi SBS,

The cause of having an OpenID account is having signed up with an OpenID provider. If you have an account at Google or Facebook, then you are signed up and can log into Web sites that display a box prompting for login with OpenID Connect with your credentials for those sites.

Or were you referring to something, errr, more philosophical?
