Frequently asked questions
What is a passphrase?
A passphrase is 3-8 random English words combined with a separator. They are easier to remember than random characters and just as secure when long enough (4+ words).
How is the strength scored?
By entropy in bits — derived from the character set size and length. 75 bits is strong; 100+ is excellent.
Is this password generator safe?
Yes. Passwords are generated locally using crypto.getRandomValues — cryptographically secure randomness. Nothing is sent or stored.
What length should I use?
16 characters minimum for random passwords, or 4+ words for passphrases. For PINs, 6 digits is standard.
