Long-lived API keys, SSH keys, and passwords are compounding liabilities; replacing them with ephemeral credentials solves rotation pain by design.
Key Takeaways
Ephemeral credentials (valid ~1 day or less) make rotation automatic, eliminating outages from stale docs and botched rollouts.
EC2 Instance Connect replaces persistent SSH keys with temporary credentials tied to a live auth/authz check.
PyPI Trusted Publishers lets GitHub Actions workflows mint short-lived package-release tokens, replacing static tokens that spread across pipelines.
SSO replaces per-app passwords with short-lived signed assertions from an IdP; attackers cannot guess a signed XML document.
For unavoidable long-lived keys: limit scope, reason through cryptographic usage limits (e.g., AES-GCM forgery risk after 2^32 messages), and rotate at least quarterly.

@pfg_: flagged a UX artifact – fixed-position background looked like phone screen dust – unrelated to the article’s security content.
