Abstract

This document defines a mechanism for HTTP/2 and HTTP/3 clients to provide additional certificate-based credentials after the TLS handshake has completed, using TLS Exported Authenticators. Unlike traditional client authentication during the TLS handshake, this mechanism allows clients to present multiple certificates over the lifetime of a session.
