> Knowing who an AI agent is answers the door; it does not decide what the agent may do. Where agent identity stops and Authority Finality™ begins.

# Identity Is Not Authority.

Giving an AI agent a strong, verifiable identity is necessary work. It is also the beginning of the question, not the answer.

[See Authority Finality™](https://kyeprotocol.com/authority-finality/) [More doctrine](https://kyeprotocol.com/blog/)

Knowing who the agent is answers the door. It does not decide what the agent may do once inside.

## What identity gives you

Agent identity establishes a trustworthy answer to "who is this?"

- A verifiable credential for a non-human actor.
- Authentication into systems and APIs.
- Attribution — every action traced to a named agent.

None of this is optional; authority with no identity behind it is meaningless. But authentication proves who is calling, and that is a strictly smaller claim than what they may do.

## Where it stops

Identity answers "who?" and stays silent on "may they, for what, and how far?"

A perfectly authenticated agent can still act far outside anything its principal delegated. Identity confirms the caller is who they claim; it carries no model of the purpose the delegation was granted for, the scope it covered, or the moment it lapsed. Authenticated-and-over-scoped is the canonical agent failure — the door opened to the right visitor, who then walked into every room.

- It names the actor; it never bounds the actor.
- Authentication is not authorisation — a login is not a licence.
- A known agent acting beyond its grant is still acting without authority.

## The line

Authority takes the identity as input and decides what it is entitled to do now.

KYE Protocol™ starts from the authenticated principal, resolves the delegated authority actually granted to it, and checks each action against that purpose and scope at the boundary — returning admit or deny and sealing it into a replay-verifiable [Evidence Pack™](https://kyeprotocol.com/evidence-pack/). That is Authority Finality™: identity opens the door; Authority Finality™ decides which rooms this actor may enter, and proves the decision later.

## Honest scope

KYE Protocol™ proves authority, not the truthfulness of the identity claim.

Verifying the credential itself remains the job of your identity provider, and a strong one is a prerequisite. KYE Protocol™ builds on top of it, supplying the entitlement decision identity alone cannot make — bound to the principal, provable on demand. Keep the identity. Add the authority.
