It happens quietly. Credentials expire without warning, or worse, they don’t — they just drift out of control. A token given for a quick test stays around long after the purpose is gone. Access you granted for a single project now opens hidden doors across your systems. That’s how leaks happen. That’s how breaches start.
The fix isn’t complicated. The habit is.
A quarterly check-in for API tokens is the simplest, highest-impact step you can take to cut risk and keep control. Every ninety days, list every token in your systems. Map who owns them, what scope they cover, and when they expire. Flag tokens with unknown origins. Expire anything unused. Rotate the ones that matter. Document everything.
The process works best when it’s repeatable. Treat it as a scheduled operation, not an afterthought. Automate detection so nothing gets missed. Send alerts for tokens nearing expiry. Require scope reviews during each cycle. Your goal is less “inventory” and more “control.”
