Aperçu

A strong password is long, random, and unique to each account — qualities humans are bad at inventing but a generator handles instantly. This tool builds passwords from letters, numbers, and symbols entirely in your browser, so the password is never sent over the network.

Comment utiliser (étape par étape)

1. 1

   Set the length

   Aim for at least 16 characters; longer is stronger.

2. 2

   Choose character types

   Enable uppercase, lowercase, numbers, and symbols for maximum strength.

3. 3

   Copy and store it

   Generate, copy the password, and save it in a password manager rather than reusing it.

Comment ça marche

The generator uses the browser's cryptographically secure randomness to pick characters from the sets you enable (uppercase, lowercase, digits, symbols). Length and character variety together determine entropy — the measure of how hard a password is to guess. Each extra character and each enabled set multiplies the number of possible combinations, making brute-force attacks exponentially harder.

Quand l'utiliser

Creating a unique password for a new account. Replacing a weak or reused password flagged in a breach. Generating credentials for a database, API, or service that needs a strong secret.
