+CockroachDB {{ site.data.products.cloud }} uses a service user named `managed-sql-prober` that regularly runs `SELECT 1;` queries on the cluster to monitor and report issues with SQL availability.

To explicitly enable this service user to authenticate, add the following line to your HBA configuration:
