+# SFTP
+
+In this section, we provide guides and references to use the SFTP connector.
+
+## Requirements
+
+To extract metadata from an SFTP server, the user needs to have read access to the directories and files to be catalogued.
+
+You can find further information on the SFTP connector in the <a href="https://docs.open-metadata.org/connectors/drive/sftp" target="_blank">docs</a>.
+
+## Connection Details
+

+### Port $(id="port")
+SFTP server port number. Defaults to `22`.
+$$
+
+$$section
+### Authentication Type $(id="authType")
+Authentication method to connect to the SFTP server. Choose between:
+- **Username/Password**: Authenticate using a username and password.
