How to use Passphrase

  1. 1. Choose word count. Six words is a reasonable default.
  2. 2. Pick a separator. Hyphen is easy to type.
  3. 3. Generate. Uses Web Crypto, not Math.random.
  4. 4. Store it elsewhere. This tab is not a vault.

About this tool

A handful of random words beats a 'clever' password people reuse. This is diceware-style, not EFF's official list — treat the bit estimate as a floor for this wordlist.

Entropy math

bits ≈ count × log2(list size). Independent uniform draws assumed.

Not a manager

Copy once into your password manager. Don't paste production passphrases into screenshots.
