Scoped Tokens with Expiration vs. Long‑Lived Tokens with Manual Revocation: Which Approach Ensures CI Security?

Goal
Maintain secure, least‑privilege authentication for CI pipelines while avoiding unexpected failures due to credential expiry.
Constraint & Uncertainty
npm allows scoped tokens to be created with explicit expiration dates, but the registry documentation does not clarify whether an expired token is automatically revoked or simply treated as invalid. In non‑interactive CI environments, this ambiguity can lead to silent failures or ambiguous error messages.
Two documented strategies exist:
- Use short‑lived scoped tokens that expire quickly, forcing re‑authentication.
- Use longer‑lived tokens and rely on manual revocation or audit‑log monitoring to enforce least‑privilege.
Unresolved Decision
Which strategy provides a more predictable security posture for CI/CD, given the current lack of explicit registry behavior around expired tokens?
Specific Questions
- Does the npm registry automatically revoke an expired scoped token, or does it merely reject authentication attempts?
- In a CI context, does an expired token result in a clear authentication error or a silent skip of steps?
- What are the audit‑log implications of relying on automatic revocation versus manual revocation for compliance teams?
