Le mot de passe est produit dans votre navigateur avec l'API Web Crypto (crypto.getRandomValues), qui fournit un aléa cryptographiquement sûr — la même source que celle utilisée par Bitwarden, 1Password ou KeePassXC. Aucune donnée n'est envoyée à un serveur.
Le pool utilisé pour ce générateur est : 26 minuscules. Soit 26 caractères distincts au total, ce qui correspond à environ 4.7 bits d'entropie par caractère.
Avec le pool de 26 caractères de ce générateur, un mot de passe de 16 caractères atteint environ 75 bits d'entropie. Au-delà de 80 bits, un mot de passe est considéré comme inviolable par force brute avec le hardware grand public 2026 (GPU type RTX 4090).
La CNIL recommande au minimum 12 caractères avec 4 types pour un compte standard. Le NIST (SP 800-63B) et l'ANSSI recommandent 16 caractères pour les comptes sensibles. 24 caractères ou plus pour les mots de passe maîtres (banque, e-mail principal, gestionnaire de mots de passe).
