This is NOT recommended by SAP (or me).
By default, you can’t save passwords in SAPGUI shortcuts under SAPGUI 7.10. However, if for some reason you would like the passwords to be saved for shortcuts, you could follow the steps below, and edit the (existing) shortcuts to save your passwords.
You will find the path HKEY_CURRENT_USER\Software\SAP
exists in the registry once you’ve installed SAPGUI 7.10
(windows cmd: regedit)
Create the following keys under HKEY_CURRENT_USER\Software\SAP:
Create a String Value under Security: ‘EnablePassword’ and set it to 1
This will allow you to save passwords for SAP Shortcuts.
To reset this to 0, run sapshcut.exe without parameters – this will reset the entry to 0.
