Shared laptops need separate accounts and a clear sign-out habit
A shared computer becomes easier to manage when each person has an appropriate account. It reduces accidental access to another person's files and makes settings more understandable.
Set up the basics
Use the operating system's official instructions to create separate accounts with suitable permissions. Keep administrator access limited to people who need it. Choose age-appropriate controls for children and discuss what those controls mean.
Close the session properly
Sign out of personal services and lock or sign out of the computer account when finished. Be careful about saving credentials on a device used by people you do not trust. Browser profiles can help organise activity, but they are not always a security boundary equivalent to separate operating-system accounts.
Keep maintenance shared
Agree who handles updates, storage and backups. Before deleting an account, check for files that need preserving with the owner's permission. This practical arrangement cannot prevent every mistake, but it reduces the chance that a family member opens the wrong inbox or changes another person's settings simply because the last session was left active.
