# Configure SingleStore User Accounts

> **⚠️ Warning**: By default, user accounts are configured independently on each SingleStore aggregator node. Whenever you add a new aggregator node, you will also need to configure user accounts on it. Users do not normally connect to leaves, so it is generally not necessary to configure user accounts on leaf nodes. Only the `root` user is required on leaf nodes.

Also, you can automatically synchronize non-root user accounts across your cluster to avoid manually managing these accounts on each aggregator node. See [Synchronizing Permissions Across Your Cluster](https://docs.singlestore.com/db/v9.1/security/administration/synchronizing-permissions-across-your-cluster.md) for more details on how to enable this functionality.
