Passphrase Generator
Build passwords you can actually remember. This generator stitches together random words from the EFF Diceware list into memorable passphrases like "copper-violet-gantry-owl". More words mean exponentially more strength — and far less frustration than random symbols.
It is completely free, private and requires no signup.
Each added word multiplies the passphrase strength while staying easy to remember.
Five words already give about 65 bits of entropy with the EFF list; six is stronger.
Use a unique passphrase per important account, kept in a password manager.
Inserting a symbol satisfies strict password policies without hurting memorability much.
How it works
Build passwords you can actually remember. This generator stitches together random words from the EFF Diceware list into memorable passphrases like "copper-violet-gantry-owl". More words mean exponentially more strength — and far less frustration than random symbols.
Five words is a solid everyday choice; use six or more for email, banking or your password manager master phrase.
Hyphens are easy to type; spaces are the strongest. Add a random digit or symbol if a site forces complexity rules.
Generate, then save the passphrase in your password manager. It never leaves your browser and is never transmitted.
Examples & Data
| Words | Example passphrase | Entropy |
|---|---|---|
| 4 | gantry-violet-owl-copper | ~52 bits |
| 5 | gantry-violet-owl-copper-suburb | ~65 bits |
| 6 | gantry-violet-owl-copper-suburb-comet | ~78 bits |
| 8 | gantry-violet-owl-copper-suburb-comet-mango-pilot | ~103 bits |
Each extra word adds about 13 bits, doubling the number of guesses roughly 8,000 times.

A password made of several random words. Because length matters more than character variety, a 5-word passphrase is both stronger and easier to remember than "P@ssw0rd!".
Yes. Six words from a 7,776-word list carry about 78 bits of entropy — comparable to a 12-character fully random password, and much easier to type on a phone.
The EFF large Diceware wordlist: 7,776 short, unambiguous English words chosen so each roll of five dice maps to one word.
Only if a site demands them. They add a little entropy but hurt memorability — extra words are almost always the better trade.
