How it works
Diceware generates passphrases by randomly selecting words from a wordlist of 7,776 entries by simulating rolls of six-sided dice using your browser's secure random number generator. Passphrases of six words or more are considered safe for high-security applications. No data ever leaves your browser.
- Pick a number (5–9) to generate that many words
- +1 appends a word, +sym appends a special character, and shuffle randomly reorders your passphrase
- Roll two or five physical dice, type the result (2 digits for a symbol, 5 for a word) using digits 1–6, and press Enter
