10 digits · pool : 10 characters
Random numeric code composed only of digits (pool of 10), ideal for card codes, smartphones or 2FA.
Previews produced with the 10 digits pool. Regenerated on each page load.
Recommended lengths depending on the use case. The longer your numeric code, the more resistant it is to attacks.
4-digit code (bank card, basic smartphone). Low security.
6-digit code recommended for smartphones and banking apps.
8-digit code for sensitive accounts that only accept digits.
Long numeric code when the interface allows it. Very strong for a PIN.
Adjust the length slider according to the intended use of the numeric code. The longer, the more secure.
Enable ambiguous character exclusion if you need to type it manually (0/O, 1/l/I).
Click copy to retrieve the numeric code from the clipboard. Regenerate as many times as needed.
Screen lock for phones, tablets or mobile banking apps.
4-digit confidential code for payment cards.
Temporary codes (OTP) or numeric backup codes for two-factor authentication.

Le code numérique 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 : 10 chiffres. Soit 10 caractères distincts au total, ce qui correspond à environ 3.3 bits d'entropie par caractère.
Avec le pool de 10 caractères de ce générateur, un code numérique de 6 caractères atteint environ 20 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).
Pour un PIN, 4 chiffres correspondent au minimum (cartes bancaires), 6 chiffres sont recommandés pour les smartphones et la 2FA (TOTP/OTP), et 8 chiffres ou plus pour les comptes sensibles. Évitez les séquences évidentes : 1234, 0000, 1111, 1212, votre date de naissance.
