Passphrase Generator

How to use this passphrase generator

A passphrase is a password built from several random words strung together. Four to six words chosen from a broad wordlist gives you 45-65 bits of entropy — strong enough for most accounts while remaining easy to type from memory. The diceware method has been the gold standard since Arnold Reinhold published it in 1995, and NIST SP 800-63B explicitly recommends long memorable passphrases over short complex ones.

1. Pick a word count. Four words is the floor for entropy. Five or six words covers email, banking, and your password-manager vault password.
2. Choose a separator. A dash, space, dot, or underscore between words makes the phrase easier to read and does not meaningfully reduce strength. Separator characters are predictable — they are for your eyes, not entropy.
3. Capitalize (optional). Title-case every word if the site requires an uppercase letter. It does not add much entropy but unlocks complexity-rule compatibility.
4. Append digits (optional).A trailing two-digit number satisfies "must include a number" rules without hurting memorability.
5. Generate and copy. Press Generate until you get a phrase you can picture in your head. The draw is cryptographically uniform, so reroll as many times as you like.

A note on wordlist size. This generator pulls from a curated English list. With a 600-word list and six random words, you get about 55 bits of entropy — comparable to a random 9-character password with lowercase, uppercase, digits, and symbols, but far easier to remember. Pair with a password manager for the sites you do not need to type by hand.
