Zero Trust Auth*
Welcome to the official Zero Trust Auth* (ZTAuth*) open protocol specification.
ZTAuth* is a Zero Trust compliant protocol for secure, identity-based access at the application edge. It supports eventual consistency and resilient synchronization across network disruptions. Built with a delegation-first model, it is ideal for systems that require secure and auditable delegation.
Pronounce it Zee-Tee-Auth-Star. The star is a wildcard, hinting at extras like trusted elevation or delegation.
For short, use ZTAStar (Zee-Tee-Ei-Star).
ZTAuth* does not replace existing standards. It adds a separate layer for fine-grained and repeatable authorization, supporting both human and non-human identities, and meeting Zero Trust security requirements.
