Benefits and Caution

  • Locking your computer keeps your computer and account secure during brief breaks.
  • It also eliminates the disruption of logging all the way out and then back in again.
  • When locking your computer, log all the way out if you will be away for a longer period of time (e.g., overnight or vacations) to avoid a dropped network connection and unsaved changes.
