Why passphrases?
Passphrases like correct-horse-battery-staple are often more secure than complex passwords because they're longer and harder to crack, while being easier to remember.
A 4-word passphrase from this 768-word vocabulary has approximately 38 bits of ideal entropy. Each additional randomly selected word adds about 9.6 bits.
Bulk Generation
Generate in Terminal
For production systems, consider generating passphrases locally:
Linux (using system dictionary)
shuf -n 4 /usr/share/dict/words | tr '\n' '-' | sed 's/-$//'Python (with custom wordlist)
python3 -c "import secrets; words=['apple','banana','cherry',...]; print('-'.join(secrets.choice(words) for _ in range(4)))"
