We are launching mot-de-passe.xyz: a complex (and post-quantum) password generator, free and with no account required



A 100% free generator, with no sign-up, no cookies and no trackers, hosted in France (Hostinger). Two modes (Classic and Post-Quantum), a real-time entropy gauge, a "Phoneme" mode for memorable passwords, and dictionary-based passphrases in 100 languages. Auto-copy (single result), CSV export (multiple results), and an open API.



A generator designed for today... and for tomorrow



Massive credential leaks and the rise of automated attacks demand secrets that are longer, more unique and more measurable.

With mot-de-passe.xyz, our goal is to make security simple for the general public and rigorous for professionals: everything runs in the browser (Web Crypto), no data is sent to the server, and the application works offline (PWA).


Two main modes

  • Classic: set the length, character sets (a-z, A-Z, 0-9, symbols), exclude ambiguous characters, enforce minimums (e.g. at least 2 digits).

  • Post-Quantum: target high entropy (e.g. 100-150 bits) with a dual gauge: "classic" bits and a post-quantum estimate (approximately H/2). The generator suggests increasing length or complexity if the threshold is not met.


New features that make the difference

  • "Phoneme" mode (FR/EN): creates pronounceable pseudo-words to make memorization easier, then automatically hardens them (digits, symbols, uppercase) to reach the target entropy.

  • Dictionary-based passphrases: Diceware wordlists in 100 languages (loaded on demand), with optional transliteration and removal of diacritics.

  • Real-time entropy display for every result (classic & post-quantum).

  • Auto-copy when generating a single password; list + CSV export when generating multiple passwords.

  • Quick presets: 24/32 characters, 10/12 words, plus a policy tester to align with your internal requirements.

Privacy & compliance

  • 0 cookies, 0 trackers - GDPR by design.

  • 100% local execution in your browser (Web Crypto).

  • PWA: works offline, with cached wordlists.

  • Hosted in France (Hostinger).

A public API, free and with no account

Integrate password generation directly into your scripts and applications: open API, free, no account required and no logging. Light rate-limiting, no logging of sensitive content.

How to use it?

  1. Choose a mode: Classic, Post-Quantum, Phoneme or Dictionary.

  2. Adjust the length / number of words and the hardening options (digits, symbols, uppercase).

  3. Generate, check the entropy, then copy or export to CSV.
