Generador de contraseñas

In an era where data breaches expose billions of credentials annually, a strong, unique password is your first and most critical line of defence. Our password generator creates cryptographically random passwords of any length, using any combination of uppercase letters, lowercase letters, numbers and special symbols. Unlike human-chosen passwords that predictably lean on familiar words or dates, algorithmically generated passwords contain no exploitable patterns whatsoever.

Generating a strong password is only half the battle — knowing its strength is equally important. After generating your password here, use our Password Strength Checker to estimate exactly how long it would take a modern brute-force attack to crack it, measured in seconds, years or even millions of years. The difference between an 8-character and a 16-character random password is astronomical.

Security experts universally recommend using a different password for every account and storing them in a password manager. Never reuse passwords across services — if one service is breached, all your accounts using the same password become immediately vulnerable. Our Base64 Encoder can also be useful for developers needing to encode sensitive credentials for API authentication flows.

¿Qué hace que una contraseña sea realmente fuerte?

NIST SP 800-63B (2017) cambió el paradigma: la longitud importa más que la complejidad. Nuestro generador usa un generador de números aleatorios criptográficamente seguro (CSPRNG).

Por qué necesitas una contraseña diferente para cada sitio

Las filtraciones de datos exponen miles de millones de credenciales anualmente. Los ataques de credential stuffing prueban inmediatamente las credenciales robadas en todos los servicios.
