Frequently asked questions
What is a passphrase?
A passphrase is a password made of several random words joined by a separator, like "correct-horse-battery-staple". The method is called Diceware, and it produces passwords that are memorable but cryptographically strong.
Is a passphrase safer than a traditional password?
At equivalent entropy, they are equally safe. But passphrases achieve high entropy using words a human can actually remember and type. Five words from a 1296-word list give ~52 bits — equivalent to a 9-character random password.
Where does the wordlist come from?
We use the EFF Short Wordlist #1 (1296 words), designed for memorability and typing speed. It's a public standard, audited and used by privacy-conscious tools worldwide. Released under Creative Commons Attribution 3.0.
