About the Strong Password Generator

Content reviewed 6 August 2026

A strong password is long and random. This generator builds one from a mix of upper- and lowercase letters, numbers, and symbols, using your browser's cryptographic randomness β€” not a predictable algorithm.

Length matters more than complexity: each extra character multiplies the effort to crack it. The tool shows an entropy estimate so you can see how strong the result actually is.

Frequently asked questions

How long should a password be?+

At least 12 characters, and 16+ for anything important. Length adds security faster than swapping in symbols β€” a longer passphrase beats a short but 'complex' string.

Is the generated password sent anywhere?+

No. It's created in your browser with crypto.getRandomValues and never transmitted or stored. Copy it straight into your password manager.
