Frequently Asked Questions
How secure is this password generator?
The generator uses your browser's built-in crypto.getRandomValues() API, which produces cryptographically secure random values. No passwords are sent to any server — all generation happens locally in your browser.
What is the recommended password length?
Security experts recommend at least 16 characters for most accounts and 20+ characters for critical accounts like email and banking. Longer passwords with mixed character sets are exponentially harder to brute-force.
Should I include symbols in every password?
Yes, when the service allows it. Adding symbols dramatically increases the search space an attacker must cover. However, some systems have restrictions, so make sure to check the site's password requirements.
Can I use the same password for multiple sites?
No. If one site is breached, attackers try the same credentials across other services (credential stuffing). Always use a unique password for every account and store them in a reputable password manager.
