Build strong, unique passwords, use a password manager, turn on two-step verification, and know the warning signs of an account takeover and exactly what to do about it.
What you’ll learn
Length and uniqueness matter most: a long passphrase, different on every account, beats a short complex one reused everywhere.
Reusing passwords means one breach can unlock all your accounts; a password manager makes unique passwords easy.
Two-step verification blocks attackers even if they steal your password, so turn it on for email first.
If an account is taken over, change the password, sign out everywhere, enable 2FA, and tell a trusted adult.
