Datos clave

The password generator creates random passwords from 4 to 128 characters long from chosen sets and shows strength in bits. It runs on the server, not in the browser: the password is built on our side and sent to you over HTTPS. For important accounts a password manager’s generator that runs on your device is safer.

Precio: Gratis
Registro: No necesario
Procesamiento: On our server: passwords are created there with random_int (PHP’s cryptographic generator) and returned to the page; only the settings, not the passwords, stay in the address
Entrada: Length from 4 to 128 characters, a count from 1 to 20, character sets: uppercase, lowercase, digits, symbols
Límites: No sign-up, no rate limit in the tool itself; the response is sent with no-store so it is not cached
Resultado: Up to 20 passwords at once with a strength estimate in bits (“weak”, “medium”, “strong”, “very strong”) and a copy button

FAQ

Choose a length (12–16 characters or more), enable uppercase, lowercase, digits and symbols and click the generate button. The tool returns up to 20 passwords and shows strength in bits.

No. The password is built on our server with PHP’s random generator and sent to you over HTTPS; only the settings stay in the address. For important accounts use your password manager’s generator.

For ordinary accounts 14–16 characters with mixed sets is sensible. Strength in bits is length × log2(set size); from 80 bits the tool shows “strong”, from 128 “very strong”.

The page is served with a no-store header and is not cached. The password does not appear in the address but does pass through our server, so critical passwords are better generated locally.

No, those modes are not offered. Only random characters from the chosen sets.

Desplaza la tabla hacia los lados

Dónde somos más débiles: the password is created on the server, not on your device, there are no passphrases, PINs or lookalike exclusion, and no saving or breach check.

Cuándo elegir PromoPilot: When you need quick random passwords for tests, throwaway accounts or something unimportant. For bank, email and work accounts use a password manager where generation happens locally.
