Australian Cyber Security Centre says:
Passwords are passé. It’s time to use passphrases instead. As we have increased our reliance on passwords, adversaries have developed increasingly sophisticated ways to crack them. In attempting to make passwords stronger, we have made them harder for humans to remember, and easier for machines to crack.
A passphrase uses four or more random words as your password. For example, ‘crystal onion clay pretzel’ or ‘red house sky train’. The longer the passphrase, the harder it is for adversaries to crack. A unique, strong passphrase can better protect your account compared to a simple password.
