Frequently asked questions
- Why use a passphrase instead of a password?
- A few random words are easy for you to remember but have enough combinations to be very hard for an attacker to guess.
- How many words should I use?
- Four or more random words make a strong passphrase for most accounts. Add more for high-value logins.
- Are the passphrases sent anywhere?
- No. They are generated locally with your browser's secure random generator.
