Generate secure, random passwords with full control over length, character sets, and special rules. Each password is created entirely in your browser using the Web Crypto API — nothing is transmitted or stored.
Generate a unique, high-entropy password for each new account instead of reusing existing ones.
Create strong API keys, database passwords, or shared secrets for infrastructure configuration.
Generate initial passwords for new user accounts that meet your organization's complexity policy.
Strong passwords need high entropy, which comes from length and character diversity. This generator lets you set both, producing passwords from cryptographically secure randomness rather than the weaker Math.random(). You can enforce or exclude specific character classes, set minimum counts for digits or symbols, and generate multiple passwords at once.
At least 16 characters for important accounts. Longer passwords with mixed character types are exponentially harder to crack.
Yes, when the generator uses the Web Crypto API and runs client-side. This tool never sends your passwords anywhere.
Absolutely — generate a strong password here, then store it in a password manager. The two tools complement each other.
All processing happens directly in your browser. Your files never leave your device and are never uploaded to any server.
