Security Measures When Using SAP Shortcuts 

SAP Shortcuts improve comfort by saving the user's logon information on the client. Users can also save their passwords in the SAP Shortcut, however, because anyone with access to the frontend client also has access to the logon information saved in the SAP Shortcut, to include the password,  we do not recommend having your users save their passwords in SAP Shortcuts.

You can also use SNC for authentication with SAP Shortcuts. For more information, see SAP Note 103019 and the SNC User's Guide at http://service.sap.com/security.
