Passphrase Generator FAQ

Are passphrases actually secure?
Yes. Each word is chosen uniformly at random with WebCrypto from the EFF diceware wordlist. A 6-word passphrase gives about 62 bits of entropy — far stronger than a typical short password, yet far easier to remember and type.
What is the EFF diceware wordlist?
A curated list of short, memorable words published by the Electronic Frontier Foundation specifically for generating random passphrases. Each word adds a fixed amount of strength because every word is equally likely.
