How to Use This Password Generator

Click "Generate" to create a strong random password. Adjust the length slider and toggle character types to match your requirements. All passwords are generated using your browser's cryptographic random number generator — nothing is sent to a server.

Are these passwords truly random?

Yes. ToolBolt uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers, the same source browsers use for TLS/SSL connections.

What makes a strong password?

Length and character diversity. A 20-character password with mixed case, numbers, and symbols has over 130 bits of entropy — effectively impossible to brute force with current technology.

Are my passwords stored?

No. Everything runs in your browser. No passwords are ever transmitted or stored. Close the tab and they're gone.

What is password entropy?

Entropy measures randomness in bits. More entropy = harder to guess. 80+ bits is strong, 100+ bits is very strong, 128+ bits is overkill for most purposes.
