How it works
- Open the Passwords tool and pick a password or a memorable passphrase.
- Adjust length, character sets, or word count to hit the strength you need.
- Copy the result. It was generated locally with
crypto.getRandomValuesand is never transmitted or stored.
Why an offline generator is safer
Any password generated on a website that talks to a server is only as trustworthy as that server's promise not to log it. FileX makes no network request at all, so there is nothing to log. Pair a generated password with the Encrypt tool for end-to-end local security.
Frequently asked questions
Are the passwords really random?
Yes — they come from crypto.getRandomValues, the browser's cryptographically secure PRNG, not Math.random. Nothing about them is predictable or seeded from your input.
