Sharing one computer with family or coworkers
When several people use the same computer, giving each person their own account keeps files and settings independent instead of tangled together -- everyone gets their own desktop, browser history, and app preferences.
Consider tighter permissions for a shared or family computer
On a computer used by a child or a guest, it's often worth keeping their account as a standard user rather than an administrator, and checking your operating system's built-in screen-time or content controls -- this limits what they can install or change without affecting anyone else's account.
Frequently Asked Questions
What's the difference between a standard and an administrator account?
An administrator account can install software and change system settings; a standard account is restricted from those changes, which makes it the safer default for everyday use.
Does deleting an account also delete its files?
You're usually asked whether to keep or delete that account's files when you remove it, so back up anything important beforehand just in case.
