Complete Guide to Password Security
Strong passwords are your first line of defense against cyber attacks. Our generator uses the Web Crypto API (crypto.getRandomValues) โ the same cryptographic standard used in security applications โ to create truly random passwords.
Why Strong Passwords Matter
Hackers use tools that try millions of combinations per second. A simple 6-character lowercase password can be cracked in seconds. A 16-character password with mixed characters would take billions of years to crack with current technology.
Password Best Practices
- Use at least 16 characters for maximum security
- Include all character types โ uppercase, lowercase, numbers, symbols
- Use a unique password for every account
- Enable two-factor authentication wherever possible
- Store passwords in a reputable password manager
- Never share passwords or reuse them across sites
Password Strength Guide
- Weak โ Short, single character type, easily guessed
- Medium โ Moderate length with some variety
- Strong โ 16+ characters with all character types enabled
Frequently Asked Questions
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness suitable for security-sensitive applications.
Never. All password generation happens entirely in your browser. No passwords are stored, logged, or sent to any server. Your passwords never leave your device.
We recommend at least 16 characters with all character types enabled. For highly sensitive accounts like banking, use 20+ characters.
Yes. Since strong passwords are difficult to memorize, a reputable password manager (like Bitwarden, 1Password, or Dashlane) is the best way to store them securely while using unique passwords for every account.
