Password Generator

Generate a strong password — free and private

Reused and guessable passwords are behind most account break-ins. The fix is simple in principle — a long, unique password for every account — but nobody can invent those on the spot. This generator does it for you: a fresh, strong password on demand, in random or memorable form, created entirely in your browser. Nothing is uploaded, so the password you generate is seen by no one but you.

That last point matters more than it sounds. A password is the one string you should never hand to a third party — yet plenty of online generators create it on their server. Here the work happens locally on your device, so there is nothing to intercept, log, or leak.

Random or memorable

Random mode produces a scramble of letters, digits, and symbols — the strongest kind of password for its length. You control the length and which character sets are included, and you can exclude look-alike characters (0 and O, 1 and l and I) so it's easier to read and type. Random passwords are best stored in a password manager rather than memorised.

Memorable mode builds a passphrase from real words with a separator and an optional number — something like Tiger-Blue-42. It's easier to type by hand or read aloud, and its strength comes from length: more words means a stronger phrase. This is the practical choice for the handful of passwords you actually have to type, like your device login or your password manager's master password.

What makes a password strong

Two things: length and unpredictability. Length is the biggest lever — each extra character multiplies the number of possibilities an attacker must try. A mix of character types helps too, but a long password made of words can be stronger than a short one full of symbols. The strength meter reflects both as you adjust the settings, so you can see the effect of adding length or another character set immediately.

As a rule of thumb, aim for 16 characters or more for a random password, or at least four words for a memorable one. And never reuse a password across accounts — a unique one per site means a breach in one place can't unlock the others.

Why in-browser generation is safer

A password generator is only as trustworthy as where the randomness comes from and where the result goes. This tool uses your browser's cryptographically secure random source (the Web Crypto API's getRandomValues), not the predictable Math.random that some scripts rely on. And because the password is generated on your device and never transmitted, there is no server that could store it, no request that could be logged, and no network path where it could be captured.

Generate several at once

Setting up multiple accounts or rotating a batch of credentials? Generate 5, 10, or 20 passwords in one go, each with its own copy button, plus a "copy all" option. Every one is produced with the same crypto-strong randomness as the single result.

Privacy: your passwords never leave your device

Everything — the randomness, the character sets, the word list — lives in your browser. Passwords are never uploaded, never stored, and never logged. There is no account and nothing to clean up afterwards; when you close the page, the passwords are gone, because they were only ever on your device.

Frequently asked questions

What's the difference between a random and a memorable password?

A random password is a scramble of characters — very strong, best kept in a password manager. A memorable one strings words together with a separator and number, easier to type while still long.

Is it safe to generate a password here?

Yes. Passwords are created in your browser with the cryptographically secure generator (crypto.getRandomValues), and nothing is sent to a server, logged, or stored.

How long should my password be?

16 characters or more with mixed types is strong for most accounts; longer is better. For a memorable passphrase, use at least four words.

Are generated passwords uploaded to a server?

No. Everything happens in your browser — passwords never leave your device, and nothing is stored or sent anywhere.
