Gerador de Senhas
Crie senhas fortes e aleatórias para manter suas contas seguras!
O que é o Gerador de Senhas?
The Password Generator creates strong, random passwords that are virtually impossible to crack through brute force attacks. In an era of frequent data breaches, using unique, complex passwords for each account is one of the most important steps you can take to protect your digital security. A typical 8-character password with only lowercase letters can be cracked in minutes, while a 16-character password mixing uppercase, lowercase, numbers, and symbols would take billions of years with current technology. Password strength increases exponentially with length and character variety. This tool generates cryptographically secure random passwords entirely in your browser. Customize length, character types, and exclusion rules to meet any website's password requirements. No passwords are stored or transmitted — everything happens locally on your device.

Perguntas frequentes
▶Essas senhas são seguras?
Sim! As senhas são geradas usando o gerador criptográfico do seu navegador (crypto.getRandomValues). Nenhuma senha é enviada a qualquer servidor.
▶O que torna uma senha forte?
Uma senha forte tem pelo menos 12 caracteres e inclui uma mistura de maiúsculas, minúsculas, números e símbolos.
▶Minha senha é armazenada em algum lugar?
Não. Tudo é executado no seu navegador. Suas senhas nunca são transmitidas ou armazenadas.
▶How long should my password be?
At minimum 12 characters, ideally 16 or more. Each additional character exponentially increases security. A 16-character mixed password is virtually uncrackable with current technology, while an 8-character password can be broken in hours.
▶Should I use a different password for every account?
Yes, absolutely. If one service is breached and your password is exposed, reused passwords give attackers access to all your other accounts. Use a password manager to store unique passwords for each service.
▶Are generated passwords stored anywhere?
No. Passwords are generated using your browser's built-in cryptographic random number generator and are never sent to any server. Once you close or navigate away from the page, the generated password exists only where you copied it.
