Perguntas Frequentes
Are generated passwords secure?
Yes, the passwords are generated using random character selection in your browser. For maximum security, use at least 12 characters with a mix of uppercase, lowercase, numbers, and symbols. The longer and more varied your password, the harder it is to crack.
Does this tool store my passwords?
No, absolutely not. All password generation happens entirely in your browser using client-side JavaScript. Your passwords are never sent to any server, stored in any database, or logged anywhere. Once you leave the page, the generated passwords exist only where you saved them.
How long should my password be?
Security experts recommend at least 12-16 characters for strong passwords. Longer passwords are exponentially harder to crack. For highly sensitive accounts like banking or email, consider using 20+ characters with all character types enabled for maximum protection.
