What Is an Ephemeral Build Credential?
An ephemeral build credential is a short-lived secret minted at the start of a build and discarded or expired when the build ends. Rather than a long-standing key stored in the pipeline, the system generates a fresh credential per run. Its brief lifetime sharply limits the value of stealing it.
Why it matters
Long-lived credentials remain dangerous indefinitely once leaked, while ephemeral ones expire before an attacker can usually exploit them. They pair well with federated identity that issues tokens on demand.
