Bootstrap tokens are used for establishing bidirectional trust between a node joining
the cluster and a master node, as described in [authenticating with bootstrap tokens](/docs/reference/access-authn-authz/bootstrap-tokens/).

`kubeadm init` creates an initial token with a 24-hour TTL. The following commands allow you to manage
such a token and also to create and manage new ones.
