API Credential Rotation

Overview

API credential rotation limits how long a compromised or overexposed credential remains useful. The process generates a replacement, distributes it through approved channels, updates clients, validates successful use, and revokes the old credential after a controlled overlap period.

Rotation may be scheduled or triggered by staff changes, suspected leakage, cryptographic policy, vendor requirements, or security incidents. Poorly coordinated rotation can interrupt production, while indefinite overlap leaves the original exposure unresolved.

Reliable systems support multiple active versions briefly, automate secret delivery, monitor old-key usage, and provide rollback without restoring an unsafe credential. Rotation plans should also address dependent services, emergency revocation, audit evidence, and credentials embedded in offline or third-party systems.

For API Credential Rotation, production scope should name the relevant endpoints, objects, workloads, secrets, dependencies, and tenant boundaries, the decision being supported, the accountable owner, and the time and jurisdiction boundaries.

API Credential Rotation is a security mechanism or control discipline that replaces an existing key, secret, certificate, or token with a new one while retiring the previous credential. Credential rotation reduces exposure duration only when the old credential is actually revoked and all dependent clients migrate safely.

For API Credential Rotation, the trust decision should establish a security mechanism or control discipline that replaces an existing key, secret, certificate, or token with a new one while retiring the previous credential and bind the result to the requested action and protected resource. Teams should test issuance, storage, validation, expiry, revocation, recovery, and privileged override for security mechanism, secret, and certificate, rather than checking only a successful request. Logs concerning the API Credential Rotation context and security mechanism, secret, and certificate should support investigation without exposing reusable secrets or unnecessary personal data.
