OpenClaw Secrets Management on Hetzner: API key hygiene, rotation runbooks, and least-privilege token design

Abstract: When OpenClaw incidents escalate, credentials are often the hidden root cause. A leaked Telegram token, an over-scoped API key, or a stale service secret can break automation, weaken access boundaries, and turn a small issue into a long outage. This guide gives a practical SetupClaw baseline for secrets management on Hetzner: classify secrets clearly, scope them with least privilege, rotate them with a safe sequence, and validate Telegram plus cron behaviour after every change.

A token is never rotated because “it still works.” A secret lands in a markdown note for convenience. Then one incident appears and suddenly three systems fail together. That is why SetupClaw treats
