Sharing family devices
Many families share devices — a tablet, a computer, or a smart TV. Sharing devices is completely normal, but it requires extra care to keep everyone’s information private and the device safe for everyone who uses it.
The most important rules for shared devices: always use your own account when you log in, always log out when you are done, and never save passwords on a shared device. These simple habits protect your privacy and everyone else’s.
Shared device rules: Log out of your accounts when finished. Do not save passwords on shared devices. Do not look at other family members’ files or messages. Tell a trusted adult if you find something concerning on a shared device.
Why separate accounts matter
Privacy Each person’s files, messages, and browsing history stay separate and private. Personal settings Your wallpaper, bookmarks, and preferences are yours — they do not affect other users. File safety Your files cannot be accidentally changed or deleted by another user. Security If one account is compromised, other accounts on the same device are not automatically affected. Parental controls Parents can set age-appropriate restrictions on a child’s account without affecting their own. Usage tracking Screen time and app usage can be tracked per account, making it easier to manage.
What happens if you do not log out?
If you leave your accounts open on a shared device, the next person who uses it can access your email, social media, games, and any other accounts you were logged into. They could read your messages, post as you, or even change your passwords.
This is not just a privacy issue — it is a security issue. Always log out of every account before stepping away from a shared device.
