+* **Workload Identify Federation (WIF) is now the default authentication type for {product-title} clusters on {GCP}.**
+In alignment with the principle of least privilege as well as Google Cloud's preferred method of credential authentication, WIF is now the default authentication type when creating an {product-title} cluster on {GCP}. WIF greatly improves an {product-title} cluster's resilience against unauthorized access by using short-lived, least-privilege credentials and eliminating the need for static service account keys.
