Password generator. Strong, random, gone when you leave.
Strong random passwords and memorable passphrases, drawn from your device's secure crypto RNG, never Math.random. A live strength meter shows the entropy. Nothing is uploaded and nothing is stored.

0 bits of entropy
Generated entirely in your browser with crypto.getRandomValues. Passwords are never transmitted or saved, close the tab and they're gone.
§ 02 · what you can do
Everything a password tool should do.
- Generate random passwords from 6 to 64 characters with full control over uppercase, lowercase, digits and symbols.
- Switch to passphrase mode for 3 to 8 real words joined by your chosen separator, easier to type and remember.
- Exclude ambiguous characters like O, 0, I, l and 1 to avoid transcription errors when reading passwords aloud.
- Enforce no repeated characters for extra uniqueness in shorter passwords.
- Bulk-generate 10 at once and copy any individual result with a single click.
- Read the live entropy meter in bits to instantly understand how strong each result is.
§ 03 · how to use it
Five steps, no manual.
- Choose Random or Passphrase mode with the toggle.
- In Random mode, set the length with the slider and tick the character types you want.
- In Passphrase mode, pick the number of words, a separator, and whether to capitalize words or append a number.
- Click Generate for one result or Generate 10 for a bulk list, the strength meter updates instantly.
- Click the copy icon next to any password to send it to your clipboard.
§ 04 · faq
Frequently asked questions.
Is the Password Generator free?
Yes, completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Are my passwords sent anywhere?
No. Everything runs in your browser on your own device. No passwords are transmitted to a server, nothing is logged and nothing is stored. Close the tab and the passwords are gone.
What is the difference between Random and Passphrase mode?
Random mode produces a string of characters from a pool you define (letters, digits, symbols), maximally compact and hard to crack. Passphrase mode strings together several real words with a separator. Passphrases are longer in characters but far easier to type and remember, while still delivering strong entropy from a large word list.
What does the entropy number mean?
Entropy in bits estimates how many guesses an attacker would need on average. Roughly 60+ bits is fair for most accounts and 90+ bits is excellent for sensitive ones. The meter updates live as you change options.
Does it work offline?
Yes. Once the page has loaded, the tool keeps working with no internet connection, the word list and all logic are bundled in the page.
How random are these passwords, really?
Every character is drawn from your browser's
crypto.getRandomValues, the same cryptographically secure random source used for encryption keys, never the predictable Math.random. We also use rejection sampling so no character or word is even slightly more likely than another.Published · Last updated .
