What is a passphrase?

A passphrase is a sequence of random words — like ocean-flame-apple-ridge. It's easier to memorize than a string of random characters, and with 4 words it achieves 28+ bits of entropy per word, totaling over 100 bits — the same ballpark as a strong random password.

When should I use a passphrase vs. a password?

Use a passphrase when you need to type it from memory — your password manager master password, a system login, or disk encryption. Passphrases are far easier to recall and type without mistakes.

Use a random password for accounts where your password manager fills it in automatically. For those, length and randomness matter more than memorability.

How many words do I need?

4 words gives you ~112 bits of entropy — strong enough for nearly any purpose. 5 words (~140 bits) is excellent for high-value accounts like your password manager master password. Going beyond 6 words adds more security than any realistic attack requires.
