Frequently Asked Questions
How long should my password be?
Security experts recommend passwords of at least 12-16 characters. Longer passwords are exponentially harder to crack. Our generator supports up to 128 characters for maximum security. For important accounts, use 16+ characters with a mix of letters, numbers, and symbols.
What makes a password strong?
A strong password has: at least 12 characters length, a mix of uppercase and lowercase letters, numbers, special symbols (!@#$%^&*), no dictionary words or personal information, and is unique for each account. Avoid patterns like "123" or keyboard sequences like "qwerty".
Is this password generator safe to use?
Yes, this generator is completely safe. All passwords are generated locally in your browser using cryptographically secure random number generation (crypto.getRandomValues). No passwords are sent to any server or stored anywhere.
How often should I change my passwords?
Modern security guidance suggests changing passwords only when there is evidence of compromise, rather than on a fixed schedule. Instead, focus on using unique, strong passwords for each account and enabling two-factor authentication (2FA) when available.
