When users, who are signed-in to the Kentico administration interface, leave their workstations unattended, someone else can tamper with the system. For this reason, Kentico allows you to set up automatic screen locking. This feature locks the working area of the browser with the administration interface after a specified time of inactivity. The users can unlock the screen after typing their password.
When using Windows authentication, this feature does not work, as unlocking the screen would not require a password. The screen locking feature is useful only in a combination with the forms authentication or the mixed mode authentication.
