Password Generator
Create strong and secure passwords, 100% in your browser
100% local analysis — your password is never transmitted
Why use our password generator?
Creating a strong password by hand is counter-intuitive: humans produce predictable patterns that dictionary attack tools crack in seconds. A cryptographic generator removes that bias — each character is picked at random from an entropy source provided by your browser (crypto.getRandomValues()), the same one used by HTTPS connections.
Our tool runs entirely locally: no network request, no cookie, nothing is ever sent to our servers. Close the tab and the generated password is gone — you are the only one who ever saw it. The code is published under the MIT License, auditable by anyone.
Classic or passphrase: which one?
Two modes are available. Classic mode produces 8 to 128 character strings with letters, digits and symbols — ideal when a password manager remembers everything for you. Passphrase mode generates a sequence of random words drawn from word lists in Luxembourgish, French, English or German — easier to retype by hand when a manager isn’t available.
A built-in strength tester analyses any password (yours or one from another generator) and displays the entropy in bits along with the estimated brute-force cracking time.
