Generatore di password
Robuste e casuali
Informazioni su questo strumento
Generate strong, cryptographically random passwords with adjustable length and character classes. Use it when you need to create a fresh password for an account, generate a temporary password to share over a separate channel, or seed a list of accounts.
Privvert uses the browser's secure random source (window.crypto.getRandomValues) - the same source banks and password managers use - so generated passwords are unpredictable and safe. Nothing is logged or sent anywhere.
Funzionalità

- Toggle uppercase, lowercase, digits, symbols
- Exclude ambiguous characters (l, I, 1, O, 0)
- Bulk generate (e.g. 20 at once for batch use)
- Strength meter (entropy in bits)
- Browser-only - passwords never logged or sent
- Free and unlimited

Tutto avviene all'interno del tuo browser con JavaScript e WebAssembly. I tuoi file non vengono mai caricati su un server, mai memorizzati e mai visti da noi.
Domande frequenti
Yes - generated with window.crypto.getRandomValues, which uses the operating system's cryptographic random source. The same source used by password managers, browsers and crypto libraries.
16+ characters with mixed classes is comfortably safe against offline attacks. Use 24+ for high-value accounts (banking, email, password manager master).
Lowercase l and uppercase I, capital O and zero - they look the same in many fonts. Excluding them helps when a password might need to be typed by hand or read aloud.
No - store them in a password manager (1Password, Bitwarden, KeePassXC). Memorizing one strong master password and letting the manager handle the rest is the modern best practice.
