API tokens are the keys to systems that run everything from billing to deployment pipelines. They let engineers interact with services without using passwords. They are powerful, dangerous, and easy to misuse. Too often, teams treat them as afterthoughts—long strings pasted into configs and left to rot. For on-call engineers, stale or inaccessible tokens mean delays, incomplete triage, and costly downtime.
The core challenge is balancing security with speed. Permanent API tokens are risks waiting to be exploited. Rotating them manually for dozens of services is a nightmare. Yet temporary access models are rare, and homegrown solutions often rely on fragile tooling.
On-call access demands a different approach. The ideal system issues short-lived API tokens on demand, scoped only to the services and actions needed to fix incidents. It should integrate with identity providers, log every access, and expire credentials automatically. Tokens should flow into engineer tooling without manual copy-paste, reducing room for error while keeping secrets short-lived.
