 Rancher v2.8.0 introduced the [Rancher Kubernetes API](./api-reference.mdx) which can be used to manage Rancher resources through `kubectl`. This page covers information on API tokens used with the [Rancher CLI](../reference-guides/cli-with-rancher/cli-with-rancher.md), [kubeconfig files](../how-to-guides/new-user-guides/manage-clusters/access-clusters/authorized-cluster-endpoint.md#about-the-kubeconfig-file), Terraform and the [v3 API browser](./v3-rancher-api-guide.md#enable-view-in-api).
 
 By default, some cluster-level API tokens are generated with infinite time-to-live (`ttl=0`). In other words, API tokens with `ttl=0` never expire unless you invalidate them. Tokens are not invalidated by changing a password.
