Why Diceware?
- •Passphrases are easier to remember than random character strings
- •Each word adds ~9.3 bits of entropy — stacking words multiplies security exponentially
- •Selected from a 613-word EFF-style list using a cryptographically secure RNG
- •Resistant to dictionary attacks because the full word combination space is enormous
Generated entirely in your browser using crypto.getRandomValues() — a cryptographically secure pseudorandom number generator. No data leaves your device.
