The article argues against using long-lived cryptographic keys due to accumulating security risks and operational challenges. It advocates for ephemeral keys (valid ≤1 day) as a more secure and manageable alternative, citing examples like SSH key rotation issues. The piece emphasizes that key rotation is often problematic and ephemeral keys inherently reduce exposure.
Background
Long-lived cryptographic keys are common in infrastructure but pose security risks through leakage, stale access, and operational complexity during rotation. Ephemeral credentials are increasingly adopted in modern security practices.
