Entity Statement

Full Title or Meme

A digital document that describes a digital Entity typically signed by a trusted issuer.

On the Identity Management page different roles are defined for Entities.

The following table is the known authentication providers and some of their characteristics. Updates and corroboration are encouraged.

Category is "User" where user has complete control, "OpenID" for providers that require user permission to release information. The rest are closed in the sense that users have limited control over the release of their information. Some provide OpenID as an option when an alternate is shown.
Some sites are not authenticators, like CA (certificate authorities) or OAuth (authorization).
Many more sites exist, some are listed on the OpenID certification page. Auth0 may offload all their AuthN to Google.

Note that some of these organizations are just associations of large Enterprises.
