Strong Password Generator

Cryptographically random passwords using `crypto.getRandomValues`. Pick length, character sets, and exclude look-alikes. Generates in bulk so you can pick the best.

Features

  • True randomness from Web Crypto (no Math.random)
  • Modulo-bias-free rejection sampling
  • Toggle uppercase / lowercase / digits / symbols
  • Exclude similar characters (0/O, 1/l/I, 5/S)
  • Generate up to 50 passwords at once
  • Live entropy estimate (bits)

How to strong password generator

  1. Set length — 16 chars is a sane minimum. 20+ for sensitive accounts.
  2. Pick character sets — Symbols and digits add a lot of entropy per character.
  3. Generate — Click Regenerate for a fresh batch. Copy any password.

Frequently asked questions

Is it safe to use the Password Generator online?
Yes — and ours is safer than most. Many free online tools quietly upload your files to their servers to do the work. We don't. Everything happens inside your browser on your own device, so your files never reach the internet. There's no upload step, no server copy, and no way for us (or anyone else) to see what you're working on.
Are my files uploaded to a server?
No. There's no server-side processing here. The whole tool is a tiny app that runs in your browser — we don't even have a server that could receive your files. You can confirm this by opening your browser's network tab while you use the tool: nothing leaves your device.
Do I need to sign up or pay?
No. There's no account, no email collection, no credit card. The tool is free to use as much as you want, on as many files as you want. We're supported by a few unobtrusive ads on the page — not by your data.
Are passwords logged anywhere?
No. They're generated and discarded entirely in your browser. We have no server that sees them.
What's a good entropy?
60+ bits resists casual brute-force. 80+ resists determined offline attack. 128+ is overkill but doesn't hurt.
