Diceware Passphrase Generator
EFF wordlist passphrases — strong + memorable. Random via crypto.getRandomValues.
About Diceware Passphrase Generator
Choose how many words you want and the tool draws them at random from the EFF wordlist to build a passphrase. Each word is selected using the browser crypto.getRandomValues API, and you can regenerate or adjust the length until you have something you can actually remember.
Word selection runs locally, so the passphrases never leave your device or get logged. Diceware passphrases are easier to recall than random character strings and, with enough words, hard to guess; six or more words is a common recommendation for accounts that matter.
Frequently asked questions
- How many words should a passphrase have?
- Six words is a widely used minimum for important accounts; add more words for higher-value targets like password managers.
- Why are passphrases better than random characters?
- They reach high entropy while staying memorable, so you are less likely to write them down or reuse a weaker password.
- Is the randomness secure?
- Yes. Words are picked with crypto.getRandomValues, a cryptographically secure source, rather than Math.random.
