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.

O que torna uma palavra-passe verdadeiramente forte?

NIST SP 800-63B (2017) mudou o paradigma: o comprimento importa mais do que a complexidade. O nosso gerador usa um gerador de números aleatórios criptograficamente seguro (CSPRNG).

Por que precisa de uma palavra-passe diferente para cada site

As violações de dados expõem milhares de milhões de credenciais anualmente. Os ataques de credential stuffing testam imediatamente as credenciais roubadas em todos os serviços.
