# Restrict auto-mount of Service Account tokens
|
|
|
|
Kubernetes automatically mounts service account credentials in each pod. The service account may be assigned roles allowing pods to access API resources. To restrict access, opt out of auto-mounting tokens by setting `automountServiceAccountToken` to `false`.
