How long should my password be?

We recommend at least 12 characters for random passwords or 4+ words for passphrases. Longer is always better - aim for 16+ characters or 6 words for sensitive accounts.

Is this password generator secure?

Yes! All password generation happens in your browser using cryptographically secure randomness. No passwords are ever sent to any server.

Frequently Asked Questions

What is a diceware passphrase?

Diceware is a method for creating passphrases using random words from a curated wordlist. Despite being made of real words, the randomness makes them extremely secure. A 6-word passphrase has about 77 bits of entropy - practically unbreakable.

Which is better: passphrase or password?

Both can be equally secure. Passphrases are easier to remember and type. Random passwords are more compact. Use passphrases for accounts you need to remember, and passwords with a password manager.

How is crack time calculated?

We estimate crack time assuming 10 billion guesses per second (a powerful attacker). Real-world attacks are usually slower, so these are conservative estimates.

Is this tool secure?

Yes! All generation uses crypto.getRandomValues() for cryptographic randomness. Nothing is stored or transmitted - everything stays in your browser.
