Title

Windows Server 2019 users must be prompted to authenticate when the system wakes from sleep (plugged in). (Cat II impact)

Discussion

A system that does not require authentication when resuming from sleep may provide access to unauthorized users. Authentication must always be required when accessing a system. This setting ensures users are prompted for a password when the system wakes from sleep (plugged in).
