After entering the System Password the first time, GP will remember it so that other System-level windows can be accessed without requiring the password for each window. The password remains cached until the GP client is restarted.
Navigation: Tools >> Setup >> Company >> Setup GP PowerPack
Mark the box next to TWK-SYS: Cache System Password, then click DONE.
The feature will be enabled for the current user. Other users must restart their Dynamics GP client to enable this feature.
Using Cache System Password
The first time the System Password is required after logging-in to GP, the normal Password box will appear. If the password is entered successfully, it will not be required again until the GP client is restarted (log-out).
