About | Universal Password Generator

Why this exists

Most password tools push you toward an account or a subscription before you can generate anything useful. Universal Password Generator does one thing differently: create a cryptographically secure random password — any length, any character set — for free, instantly, with nothing to sign up for and nothing that can later be switched off or put behind a paywall.

How the generator works

Every password is generated entirely inside your own browser using crypto.getRandomValues(), the Web Crypto API built into every modern browser. This is the same cryptographically secure pseudo-random number generator (CSPRNG) used by security software and operating systems. Nothing you type or generate is ever transmitted to any server — not even anonymised. You can verify this by disconnecting from the internet and reloading the page; the tool works just the same.

How it stays free

This site is supported by advertising served through Google AdSense. There is no premium tier and no feature held behind a paywall — ads are what make every part of the tool free and unlimited. The cookie banner on the site lets you choose between personalised ads (which require consent) and non-personalised ads that run without cookies.

Privacy by design

Passwords are sensitive by definition. This tool was built so that it is technically impossible for it to see what you generate. The generation code runs in your browser, output stays in your browser, and no data leaves your device. There are no analytics that track what passwords you generated or what options you selected.

Part of the Universal family

Universal Password Generator is one of several free utility tools built on the same principle: solve one real problem well, keep it free, and respect your time. All tools share the same clean, fast design with no dark patterns, no upsells, and no friction.
