Kavi's Strong Key

Kavi's first password was just cat — short and easy to type. But a sneaky guesser tried the easy words one by one, and cat almost let them in! Kavi gulped and made a new one: Blue7Owl! — long, with big and small letters, a number, and a symbol. "Now it's far too tricky to guess!" Kavi hooted. And Kavi kept it a secret, telling only a trusted grown-up at home. A clever owl knows: a strong password is long, mixed, and hard to guess — and you keep it safe.
