The ChrysoKit Passphrase Generator builds memorable, secure passphrases from a curated word list. Cryptographically random, with the rules you actually need: separator, casing, optional digit and symbol.
Why use it
A six-word random passphrase is easier to type, easier to remember, and stronger than most invented passwords. The tool handles randomness and formatting; you handle the choosing.
How to use the Passphrase Generator
- Pick the number of words (3-10, six is recommended).
- Choose a separator: hyphen, space, underscore, dot, or none.
- Pick a case mode: lowercase, Title Case, UPPERCASE, or mixed (random).
- Tick "Add a random number" and "Add a random symbol" if a site requires them.
- Generate and copy.
Features worth knowing
Configurable structure
3-10 words. Five separators. Four case modes. Optional digit and optional symbol. Cover almost any "password must contain..." rule.
Cryptographic randomness
The word picks come from Web Crypto, not Math.random. The wordlist itself is curated for memorability and pronounceability.
Entropy estimate
Each generated passphrase shows its estimated bits of entropy so you can pick a length that matches the account's risk.
Pro tips
- Six words is the modern minimum. Four is fine only with a manager handling the autofill.
- Don't pick passphrases yourself. Human-chosen "random" words are not actually random.
- Add a digit or symbol only if a service insists. The entropy gain is small; readability suffers.
- Hyphen or dash separator is the easiest to type on every keyboard layout.
Privacy first. The Passphrase Generator runs entirely in your browser. Nothing you generate is uploaded.
Use the Passphrase Generator for accounts you actually need to type the password into, your password manager's master password is the canonical example.

The memorability experiment worth running on yourself
Generate a five-word passphrase right now and apply the technique memory researchers actually endorse: build one absurd visual scene linking the words in order. If the dice produce "marble lantern bishop circus oxygen", picture a marble lantern lighting a bishop juggling oxygen tanks at a circus. The more ridiculous, the stickier... vividness and novelty are what biological memory indexes on. Type the phrase five times today, twice tomorrow, once next week. For most people, that schedule (spaced repetition, in miniature) moves a 64-bit secret into permanent storage inside three days.
Now compare the experience against memorising "Kx7#pQ2$wN9!"... a password of equivalent strength. Most people still need the sticky note after a month, and the sticky note is the vulnerability.
This is the entire case for passphrases in one experiment: equal math, radically different human performance. Reserve the technique for the two or three credentials you must type from memory... the password manager master, the computer login, perhaps the primary email... and resist the temptation to reuse one beloved phrase across them. The phrase you can recall in a half-asleep airport at 5 a.m. is infrastructure; treat it with the same uniqueness discipline as everything else.
