Password Generator

Our passwords are generated using your browser's cryptographically secure random number generator (crypto.getRandomValues). This is the same technology used by security professionals and password managers.

The passwords are generated entirely in your browser - they are never sent to our servers or stored anywhere except in your browser's session storage (which clears when you close the tab).

Password strength is measured in "entropy" - the amount of randomness or unpredictability. A stronger password has more entropy, making it harder to crack. Key factors include:

• Length: Longer passwords are exponentially harder to crack. Each additional character multiplies the possibilities.
• Character variety: Using uppercase, lowercase, numbers, and symbols increases the pool of possible characters.
• Randomness: True random generation (like ours) is much better than human-made passwords or patterns.

A password with 128+ bits of entropy would take billions of years to crack with current technology!

Ambiguous characters are letters and numbers that look similar and can be easily confused when reading or typing:

• 0 (zero) and O (uppercase O)
• 1 (one) and l (lowercase L) and I (uppercase i)

Excluding these characters makes passwords easier to read and type manually, which is helpful when you need to enter a password on a different device or share it verbally.

The recommended minimum length depends on how the password will be used:

• 12+ characters: Minimum for most websites and services
• 16+ characters: Recommended for important accounts (email, banking)
• 20+ characters: Ideal for master passwords and password managers
• 32+ characters: Maximum security for highly sensitive data

When in doubt, go longer! With a password manager, you don't need to remember the password anyway.

Absolutely! Password managers are the best way to maintain strong, unique passwords for every account. Benefits include:

• Generate and store complex passwords automatically
• Never reuse passwords across sites (a major security risk)
• Auto-fill passwords so you don't need to type them
• Sync securely across all your devices
• Alert you if any of your passwords appear in data breaches

Popular options include 1Password, Bitwarden (free), LastPass, and the built-in password managers in browsers and operating systems.

Yes! When you share, we only share your settings (length, character types) - never the actual password. The shared link lets someone generate their own unique password using the same criteria.

This is useful for recommending password requirements to others without compromising security.
