When a data source node is added to a data source in Teradata Fabric, node software is installed on the node, and a node service registers the node with a Teradata Fabric Manager instance. The node service provides the following:
| Item | Description |
|---|---|
| UUID | Acts as the node username when the node authenticates itself to a Teradata Fabric Manager instance. |
| Time-limited access token | Authenticates the node before the node can be added to a data source for the first time. |
| Generated password for authentication | Allows the node to authenticate itself to a Teradata Fabric Manager instance after the node joins a data source for the first time. |
