THE OUTCOME
Replace durable shared secrets with short-lived, purpose-bound access wherever the system supports it.
Primary search intent: ephemeral credentials for AI agents
CORE MODEL
Four ideas before action.
Scope binds purpose
Credential permissions should identify resource, action, tenant and sometimes amount.
Issuance needs identity
The broker must authenticate the requesting agent or controller before minting access.
Revocation still matters
Compromise response cannot rely only on waiting for expiry.
ACTION CHECKLIST
A six-step review process.
- Inventory every agent secret
- Move issuance behind an authenticated broker
- Set minimal scopes and TTL
- Avoid logging raw credentials
- Rotate signing and issuer keys
- Correlate issuance with every use
