# One Auth: Unified Identity Across Every Connected System

> One Auth is Spine Innov Labs's identity layer that lets a single sign-in reach every connected tool, capability, and agent under one governed identity.

One Auth is the identity layer that makes connected work possible. A single authenticated user reaches every connected source system, capability, and agent under one governed identity, without re-authenticating or handing tokens across tools.

## What One Auth Provides

* **Single sign-in** to the workspace, propagated to every connected system.
* **Delegated identity** so agents and Twin act as you, within the boundaries you set.
* **Per-connection scopes** so each source system only sees what it needs.
* **Audit-ready identity chain** on every action written back to a source system.
