ACL Tokens

This page lets you enter an ACL token (both accessor ID and secret ID) to use with the UI. If the cluster does not have ACLs enabled, this page is unnecessary. If the cluster has an anonymous policy that grants cluster-wide read access, this page is unnecessary. If the anonymous policy only grants partial read access, then providing an ACL Token will authenticate all future requests to allow read access to additional resources.
