Password Generator
Cryptographically secure random passwords, generated in your browser via the Web Crypto API. Nothing is sent to our servers.
Options
A strong password is one that's both long enough and random enough to resist brute-force guessing and dictionary attacks. The ToolEdge Password Generator builds passwords using your browser's Web Crypto API (`crypto.getRandomValues`) — a cryptographically secure random source — and never sends the result to our servers. You pick the length and character classes; we sample uniformly from the resulting alphabet and show you the entropy in bits so you know exactly how strong the result is.
Most password leaks happen because users reuse weak passwords across services. A unique 16-character random password per service is the single highest-impact security habit you can adopt — much higher than picking complex but memorable phrases. Pair this generator with a password manager (1Password, Bitwarden, Apple Passwords) and you essentially close off credential-stuffing as an attack vector.
Common use cases
- Bootstrapping a new account — generate a 20-char password, paste into your password manager, never see it again.
- Creating service-account secrets (API tokens, database passwords) where memorability doesn't matter and length does.
- Resetting compromised credentials after a breach — generate fresh, unique passwords for every affected account.
- Generating Wi-Fi network keys: 24+ alphanumeric chars at WPA2/3 are effectively unbreakable.
- Creating throwaway passwords for short-lived test accounts or shared dev environments.
Frequently asked questions
crypto.getRandomValues, the browser's cryptographically secure pseudo-random number generator backed by the OS entropy pool. This is the same source used by HTTPS, WebAuthn, and password managers. It is *not* Math.random() (which is predictable and unsafe for crypto). Passwords are generated entirely in your browser — they are never sent to or logged by our servers.
