+# Fleet Workload Identity Authentication
+
+This page contains example configuration to configure the `gcs-fuse-csi-driver`  
+with [Fleet Workload Identity](https://cloud.google.com/anthos/fleet-management/docs/use-workload-identity) 
+authentication in environments configured for 
+[Workload Identity Federation](https://cloud.google.com/iam/docs/workload-identity-federation) 
+outside of the Google Cloud.
+
+## `external_account` Credentials
+
+Instead of the Google Service Account key file, it is possible to pass a Fleet Workload Identity configuration
+JSON file to the process that needs authenticating to the Google API in a Kubernetes cluster configured for 
+the Workload Identity Federation. The `gcs-fuse-csi-driver` pods are such processes
+that need to authenticate to the Google Cloud Storage service API to provide access to the data stores in the 
+Google Cloud Storage buckets.
+
+Such configuration file contains `external_account` type of credential that does not contain any secrets similar 
+to the Google Service Account key. The configuration should be passed via the `GOOGLE_APPLICATION_CREDENTIALS` 
+environment variable, which requires the file name of the file containing the configuration on 
+the pod's local file system.
+
+A ConfigMap to host the contents of the configuration file for the `GOOGLE_APPLICATION_CREDENTIALS` environment variable 
+of pods on Kubernetes clusters, such as Anthos on Bare Metal clusters, that require accessing Google Cloud API using 
+[Fleet Workload Identity](https://cloud.google.com/kubernetes-engine/fleet-management/docs/use-workload-identity) can be created 
+like illustrated in the following snippet:
+
+```yaml
+cat <<EOF | kubectl apply -f -
+kind: ConfigMap
+apiVersion: v1
+metadata:
+  namespace: gcs-fuse-csi-driver
+  name: default-creds-config
+data:
+  config: |
+    {
+      "type": "external_account",
+      "audience": "identitynamespace:$FLEET_PROJECT_ID.svc.id.goog:https://gkehub.googleapis.com/projects/$FLEET_PROJECT_ID/locations/global/memberships/$CLUSTER_NAME",
+      "service_account_impersonation_url": "https://iamcredentials.googleapis.com/v1/projects/-/serviceAccounts/GSA_NAME@GSA_PROJECT_ID.iam.gserviceaccount.com:generateAccessToken",
+      "subject_token_type": "urn:ietf:params:oauth:token-type:jwt",
+      "token_url": "https://sts.googleapis.com/v1/token",
+      "credential_source": {
+        "file": "/var/run/secrets/tokens/gcp-ksa/token"
+      }
+    }
+EOF
+```
+
+Please note, that the `service_account_impersonation_url` attribute in the snippet above is only necessary if you 
+link a Google Service Account with the Kubernetes Service account using `iam.gke.io/gcp-service-account` annotation
+and `roles/iam.workloadIdentityUser` IAM role. Otherwise, you can omit this attribute in the configuration.
+
+## Pass `GOOGLE_APPLICATION_CREDENTIALS`
+
+Following snippet illustrates passing the ConfigMap with `external_account` credential to the 
+`gcs-fuse-csi-driver` pods of the `gcsfusecsi-node` DaemonSet that needs Fleet Workload Identity Authentication 
+for accessing data in Google Cloud Storage buckets using the `GOOGLE_APPLICATION_CREDENTIALS` environment variable.
+
+```yaml
