Passwords are secret keys — Computing, 4–6
A password helps a device know that the right person is opening an account. Computing, 4–6 years.
A secret key
A password is a secret word, number or group of signs that opens a digital account or device. It works like a key for a lock, but you type it instead of turning it. The computer checks it without showing the secret to everyone nearby.
Why passwords exist
A device may be used by many people, but some things belong only to one person or family. Without a password, anyone holding the device might open them. The password gives the device a small question to ask: “Do you know the secret?” Ask a trusted adult before making one.
What happens at sign-in
Imagine a tablet with a drawing account. You type the name Leo, then type the secret password. The tablet compares what you typed with the saved secret. If both parts match, it opens the account; if one part is wrong, it stays locked and asks you to try again.
A password is not a name
It feels sensible to use your name or favourite animal because you can remember it easily. But someone who knows you may guess those things. A password is useful only when it is hard for other people to guess, so keep it secret and let a trusted adult help you remember it.
Where you use it
Passwords protect a tablet profile, a game or a family music account. You may see dots instead of the letters as you type, so people nearby cannot read the key. If you forget one, do not guess wildly or tell a stranger; ask the adult who looks after the account.
