Thursday: Passwords keep Wi-Fi private

A neighbor asks for the Wi-Fi password.

Rocket opens his mouth. Raven stops him.

"What do you notice about who asked?"

Nova hums. "Hint: a grown-up keeps the password."

A key for the network

A Wi-Fi network has a password.

The password is like a key to a door.

It keeps strangers off your network.

A grown-up keeps the password private.

Never share a password with anyone who asks.

If someone asks, say: ask my grown-up.

Strong passwords are long and hard to guess.

No Wi-Fi? Safe things to try
