A free random password generator that leaves no trace.

Create a strong, unique password with your browser's cryptographically secure random number generator. The result stays on this screen, is never saved to history, and disappears when you close the tab.

Generated with crypto.getRandomValues() and unbiased random selection.

01 / Local

Your browser does the work

The generator runs entirely in JavaScript on your device. There is no generation API or server request.

02 / Ephemeral

Nothing is remembered

We do not place generated passwords in cookies, local storage, session storage, logs, or a recent-history panel.

03 / Unbiased

Every character gets a fair chance

Rejection sampling avoids the subtle modulo bias found in many basic random password scripts.

One password tool does not fit every login.

Some accounts need symbols. Some devices accept digits only. Some secrets must be typed by hand. Use a generator designed for the exact job.

Long, random, and unique beats complicated-but-reused.

A strong password is not simply a short string with a capital letter and an exclamation mark. Its strength comes primarily from unpredictable selection, sufficient length, and never being reused on another account.

Practical default: Use the generated 20-character password above, save it in a reputable password manager, and enable multi-factor authentication or a passkey where available.

Why 20 characters?

Current NIST guidance requires services using a password as a single authentication factor to accept a minimum of 15 characters. A 20-character random password provides comfortable margin while remaining compatible with most websites.

Do symbols always make a password safer?

Symbols expand the possible character pool, but adding length is usually the simplest way to increase a randomly generated password's resistance. If a website rejects symbols, use the dedicated alphanumeric generator.

Where should I store it?

Use a password manager rather than a note, document, screenshot, email draft, or browser history. This website deliberately does not try to become a password vault.

Questions worth asking before you copy.

Is this password generator safe?

The generation logic runs locally with the Web Crypto API and does not save generated passwords. You can also use the generator built into a trusted password manager.

Can the website see the generated password?

No generation request is sent to a server. The password is not added to analytics, storage, a database, or a history feature.

Why is there no recent password history?

A history panel is convenient but creates unnecessary exposure on a shared computer. This site treats each result as temporary.

Should I use a password or a passkey?

Use a passkey when a service supports it and your recovery setup is sound. Passwords still matter for services without passkeys and for device or file credentials.
