Auth Schemes

OpenID Connect (OIDC) is an identity layer built on top of OAuth2. While OAuth2 is generally used for authorization, OpenID Connect extends OAuth2 to include authentication.

Basically, OAuth2 tells the client what the user is allowed to do (authorization), while OpenID Connect tells the client who the user is (authentication).

By making the association with an external id and including a means by which an authorization token can be validated, we can use both OAuth2 and OIDC for authentication within Elements.
