📖 How It Works

Cryptographically Secure Generation

This password generator uses the Web Crypto API (window.crypto.getRandomValues()) to generate truly random passwords. Unlike pseudo-random generators, cryptographic randomness is suitable for security-sensitive applications and is virtually impossible to predict.

Password Strength

The strength meter evaluates your password based on:

Length: Longer passwords are exponentially harder to crack
Character Variety: Using all character types increases combinations
Entropy: The mathematical measure of password randomness

🔒 100% Offline: Your passwords are generated entirely in your browser. Nothing is sent to any server. Even if someone monitored your network traffic, they would see nothing - because there's nothing to send.

🛡️ Password Security Tips

Use 16+ characters: Modern GPUs can crack short passwords in minutes
Never reuse passwords: If one account is breached, others remain safe
Use a password manager: Tools like Bitwarden or 1Password store passwords securely
Enable 2FA: Two-factor authentication adds an extra security layer
Avoid personal info: Never use birthdays, names, or dictionary words
Update regularly: Change critical passwords every 3-6 months

❓ Frequently Asked Questions

For most accounts, 16 characters is a good minimum. For highly sensitive accounts (banking, email), consider 20+ characters. Each additional character exponentially increases security.

Yes. We use the Web Crypto API which provides cryptographically secure random number generation. This is the same level of randomness used for encryption and security protocols.

Characters like 0/O, 1/l/I can be confusing when reading or typing passwords manually. Excluding them makes passwords easier to use without significantly reducing security.

Absolutely not. Passwords are generated using JavaScript in your browser. They exist only in your browser's memory until you close the page. We have no way to see or store them.
