Encrypt Repository Password
If your model is developed on a DBMS repository, the 'Save Project Shortcut' dialog has an 'Encrypt Connection String' check box.
You can create the shortcut actions and, if necessary, select the checkbox to encrypt the database connection string.
You distribute the shortcut file to the database users who are to access the model. The users then have an encrypted string that prevents them from directly accessing the database using other tools.
