Rotated secrets are long-lived credentials that get replaced with new ones at a set interval, offering improved control and stability. They are best suited for workloads that require continuous operation and are shared by multiple workload instances. Dynamic secrets, on the other hand, provide temporary access to resources and are generated on demand with a limited lifespan, helping prevent secret sprawl. The choice between rotated and dynamic secrets depends on systems, workflows, and security needs, and combining both approaches can provide more robust protection in many cases.
