Password Phrase Generator

Generate memorable passphrases and strong random passwords locally in your browser, without sending the generated value to CyganLabs.

Status: Live · Processing: local/browser-side only. Pick passphrase or random password mode, generate with browser cryptography, copy the result into a password manager, and clear the page when you are done.

This tool is for ordinary moments when you need a solid secret without creating an account, trusting a random generator site, or handing your password to a service you do not understand.

No accounts. No intentional storage. No server-side password generation.

Privacy: generation happens in this browser tab using crypto.getRandomValues. The tool does not intentionally send generated values to CyganLabs, log them, store them, check them, use localStorage, or put them in the URL. Normal CyganLabs page infrastructure may still load site assets, analytics, or ads; the local-processing claim is about the generated secret itself. For the safest handling, copy the generated value directly into your password manager and clear the page afterward.

Reality check: a strong generated password still needs careful handling. Do not reuse it. Save it in a password manager. Avoid pasting secrets into chat messages, spreadsheets, tickets, shared documents, or anywhere else that was not designed to protect credentials.

Passphrase mode: picks fresh random indexes from the EFF Long Wordlist. It is wordlist-based on purpose, like diceware, but it is not choosing from a list of premade passwords.

Random password mode: builds a new character string from lowercase, uppercase, number, and symbol pools. It does not use the wordlist.

Generate a secret

Passphrases intentionally use random word-list picks. Random passwords are generated character-by-character from selected pools. If a website wants a password, use random password mode and save it in a password manager.

What do you need?

Word count

Six EFF long-list words is the sane default.

Separator

Custom separator

Capitalization

Add two random digits to passphrases. Add one random symbol to passphrases. Avoid ambiguous characters in random passwords.

Result

The generated value is displayed so you can copy it. Clear it when you are finished.

Ready. Nothing has been generated yet.

Generated value

Copy it into your password manager. Do not reuse it across accounts.

When to use it

Generating a password-manager master phrase, device unlock phrase, or another secret you may need to type deliberately.
Creating a random account password that should be saved in a password manager instead of memorized.
Comparing how length, randomness, and character choices affect strength without relying on theatrical “time to crack” estimates.
Creating a fresh password when a website requires specific character rules.

How to use it

Choose whether you want a memorable passphrase or a random password.
Keep the defaults unless you have a specific password rule to satisfy.
Generate locally, copy the value into your password manager, and clear the page.
Use a different password or passphrase for every important account.

What this does not do

It does not store, remember, recover, or sync generated values.
It does not check whether a password has appeared in a breach.
It does not replace a password manager, multi-factor authentication, or careful account recovery settings.
It does not know a website’s password rules until you try them.
It does not make reused passwords safe. If one reused password leaks, every account using it becomes exposed.

Wordlist and randomness

Passphrases use EFF’s Long Wordlist, a 7,776-word list designed for dice-generated passphrases. The app includes the wordlist locally inside the page and selects words with crypto.getRandomValues plus rejection sampling, so it does not need a network call after the page loads.

Random password mode does not pull from the wordlist at all. It picks characters from the selected character pools, guarantees the selected character types are represented, then shuffles the result using crypto-backed randomness.

The entropy number is an estimate based on the size of the random choice space. It is useful for comparing settings, not a guarantee that every site, device, workflow, or human handling habit is secure. Password strength matters, but so do storage, reuse, recovery settings, MFA, and where the secret is pasted.

Questions

Does CyganLabs see the generated password?

No. Generation happens in your browser. The tool does not intentionally send generated values, settings, or clipboard contents to CyganLabs, an AI service, or a third-party password checker. Passphrase mode uses random word-list picks; random password mode generates random characters, not a prebuilt password list.

Should I use this for my bank password?

You can generate a strong value here, but the safer pattern is what you do next: save a unique password in a password manager, do not reuse it anywhere else, and turn on multi-factor authentication where available.

For high-value accounts, your password manager’s built-in generator is also a good option, especially if it integrates directly with the login form.

Why not use Math.random?

Math.random is not meant for security. This tool uses the browser’s cryptographic random source instead, then avoids modulo bias when choosing words or characters.

Are passphrases secure?

Random passphrases can be very strong when they use enough words from a large list. The important word is random: user-invented phrases tend to follow patterns, references, substitutions, and personal habits.

Let the generator do the randomness. Your job is to store the result safely and avoid reuse.
