Password vs Passphrase: Which is More Secure?
Compare high-entropy random character strings with multi-word passphrases for security and memorability.
Passwords are best for machine-enforced complexity
Random passwords with symbols and numbers are highly resistant to dictionary attacks and are often required by legacy systems that have character limits.
Passphrases offer high entropy with better memory recall
A long passphrase made of unrelated words is often more secure against modern brute-force attacks than a shorter, complex password, and is much easier to type manually.
