Password Generator

This password generator uses the Web Crypto API (crypto.getRandomValues) to generate cryptographically secure random numbers. These random values are then mapped to your selected character set (uppercase, lowercase, numbers, symbols) to create a truly random password. All processing happens entirely in your browser - no data is ever sent to any server.

Yes, the passwords are cryptographically secure. We use the Web Crypto API which provides access to a cryptographically strong random number generator. This is the same technology used by password managers and security applications. The randomness is suitable for all security-sensitive applications.

No, absolutely not. This tool runs 100% in your browser using JavaScript. Your generated passwords never leave your computer and are never transmitted over the internet. There are no server requests, no logging, and no tracking. Once you close the page, the passwords exist only if you've copied them.

A strong password typically has: 1) At least 12-16 characters in length, 2) A mix of uppercase and lowercase letters, 3) Numbers and special symbols, 4) No personal information or common words, 5) Unique for each account. Our generator helps you create passwords meeting all these criteria.

For most purposes, 16 characters is a good minimum. For high-security accounts (banking, primary email), consider 20-24 characters. For master passwords (password managers), 24+ characters is recommended. Longer passwords are exponentially harder to crack - each additional character multiplies the difficulty significantly.
