  1. Choose a type

    Pick Random for maximum security, Memorable for something easier to type, Passphrase for word-based, or PIN for digits only.

  2. Set length and options

    Use a preset (Easy → Insanely strong) or fine-tune length and character types yourself.

  3. Generate

    Hit Generate and instantly get one or many passwords — up to 500 at once.

  4. Copy or download

    Copy individual passwords with one click, copy them all, or download the full list as a .txt file.

Details edit

🔐 100% client-side

Passwords are generated by your browser using window.crypto.getRandomValues(). Nothing is uploaded, logged, or stored. The download button creates the file locally with the Blob API.

For accounts you care about, pair generated passwords with a reputable password manager and two-factor authentication.

Frequently asked questions edit

Yes. Every password is generated locally in your browser using window.crypto.getRandomValues(), a cryptographically secure source of randomness. No password is sent to any server, logged, or stored. Close the tab and they vanish.
For accounts that matter (email, banking, password managers) use at least 16 random characters. 12 mixed-case + symbols is a sensible minimum for most sites. Anything under 10 is crackable in hours by modern GPUs.
A passphrase is several random words joined together, like "correct-horse-battery-staple". Four to six truly random common words give 50+ bits of entropy — stronger than most 10-character passwords, and far easier to memorise. Add a digit or symbol for any site that demands them.
If you ever have to read the password aloud, type it from paper, or dictate it, yes — these characters look near-identical in many fonts. For password-manager-only use, leave them in; excluding characters slightly reduces entropy.
Yes. Set the "How many passwords?" slider up to 500. After generating, click "Download .txt" to save the full batch as a plain-text file. Useful for provisioning many accounts, gift cards, or one-time-use credentials.
It enforces that no character appears twice in the same password. Some legacy systems require this. For most modern use it slightly weakens randomness (passwords become a permutation rather than a sample), so leave it off unless your target system demands it.
Math.random() is a pseudo-random number generator suitable for games and animations but predictable enough to be unsafe for passwords. Crypto-grade randomness is sourced from the operating system's entropy pool and is the standard for keys, tokens, and passwords.
No. Nothing leaves your device. Look at the page source — the generator runs entirely in JavaScript in your browser. There is no upload, no analytics on the values, no server call.
