| Description | ||||
| Hot corners must be disabled. The information system conceals, via the session lock, information previously visible on the display with a publicly viewable image. Although hot corners can be used to initiate a session lock or to launch useful applications, they can also be configured to disable an automatic session lock from initiating. Such a configuration introduces the risk that a user might forget to manually lock the screen before stepping away from the computer. | ||||
