The Secure User Store for the SAP HANA client, a.k.a. hdbuserstore, can be used to safely store the connection string (server, port, username, password) as a key for secure client connections.
This SSFS (secure-store-in-the-file-system) for the SAP HANA client has been part of SAP HANA since the initial release. Using it to connect to the SAP HANA Service requires no changes in parameters or options.

In the video tutorial below, we show how you can create a user store key for macOS (Linux) and Windows, and use it with hdbsql, the SAP HANA interactive terminal, with ODBC/JDBC, in Java and in Python.
hdbuserstore -i Set HAASKEY
Viewing the key store on Linux and Windows. Note that the key is the same for on-premise SAP HANA and for the SAP HANA Service. Also note that the key is the same on Linux and Windows (or macOS). Only the path to the key and data file differs a bit.
Use the key with the interactive terminal. Works on any platform.
