Your privacy is protected. Passwords are generated entirely in your browser using cryptographically secure random number generation. Nothing is stored or sent anywhere.

How It Works

This generator uses the Web Crypto API to generate cryptographically secure random numbers. This is the same level of randomness used by security applications and operating systems.

Uses crypto.getRandomValues() for true randomness
Passwords are never transmitted over the network
No passwords are logged or stored on any server

Password vs Passphrase

Random Password

Best for: Maximum security, password managers

Example: Kj#9mP&2xL!qR

Hard to remember but very secure. Ideal when using a password manager.

Passphrase

Best for: Memorization, master passwords

Example: correct-horse-battery-staple

Easier to remember and type. Great for your password manager's master password.

Frequently Asked Questions

How long should my password be?

We recommend at least 16 characters for important accounts. For very sensitive accounts, consider 20+ characters or a 5-word passphrase.

What is entropy?

Entropy measures password randomness in bits. Higher entropy means more possible combinations, making the password harder to guess. Aim for at least 60 bits for important accounts.

Should I use a passphrase?

Passphrases are great when you need to remember the password (like a master password). For accounts where you'll use a password manager, random passwords are more efficient.
