How to Secure an API Integration That Uses a Long-Lived Access Token

A long-lived API token can continue working long after a staff member or integration changes. If it is copied into code or logs, rotation may be difficult and access can exceed what the integration needs.

What to check

Identify where the token is stored, its permissions, owner, last use, expiration options, and all consumers. Review source control and logs for accidental exposure without printing the token itself.

Recommended next step

Use a scoped service identity and approved secret storage, rotate the token through a tested process, and monitor usage after the change. Document ownership and a revocation path for emergencies.
