+Data source authentication
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The connector can provide credentials for the data source connection
+in multiple ways:
+
+* inline, in the connector configuration file
+* in a separate properties file
+* in a key store file
+* as extra credentials set when connecting to Trino
+
+You can use :doc:`secrets </security/secrets>` to avoid storing sensitive
+values in the catalog properties files.
+
+The following table describes configuration properties
+for connection credentials:
