Why Passphrases are Safer than Passwords

A passphrase is a sequence of random words. While traditional passwords like Tr0u$4# can be difficult to remember and vulnerable to dictionary and brute-force attacks, a passphrase like Cosmic-Breeze-Orbit-Proxy is easy for humans to memorize but extremely difficult for computers to crack due to its sheer character length.

Length is the single most critical factor in entropy calculations. Generating a passphrase with 4 or 5 random words provides over 60 bits of entropy, which is highly recommended for security.
