[RFC8288] defines a framework and registry for Link Relationships types. This specification defines a set of new relationship types to aid clients in discovering endpoints for authentication and registration: authenticate, authenticated-as, logout and register-user.
The authenticate can be used to link to a resource that hosts a page where a user can authenticate itself for the current resource.
For example, this link might refer to a HTML login page.
Example:
<a href="/login" rel="authenticate">Login</a>
This specification doesn’t define the authentication protocol. For example, the link could refer to an OAuth2 authorization endpoint.
The authenticated-as link refers to a resource that describes the effective authenticated user for a HTTP response.
Following this link might allow a client to answer the question ‘who am I?’. This might link to a user profile page, or it might link to an API that returns a JSON response with user information.
Example:
Link: <https://api.example.org/users/123-abc>; rel="authenticated-as"
The logout refers to a resource where an authenticated user might end their session.
In a browser this might clear cookies, or in the case of OAuth2 it could revoke any active authentication tokens.
The register-user Link Relation refers to a resource where a user might sign up for a service for the context URI.
The linked resource might contain a HTML registration form, or otherwise instructions that allow a client to find out how to sign up for the service.
This document defines authenticate, authenticated-as, logout and register-user link relation types and adds them to the “Link Relations” registry:
