About This Tool

Create genuinely strong passwords in seconds — the kind hackers hate. This generator uses your browser's cryptographic random engine (the same technology behind HTTPS security), not basic Math.random like most online generators. Choose from seven modes: a full custom generator with presets and character options, speakable passwords you can read aloud over the phone, memorable combos like Blue$Tiger392, XKCD-style passphrases like correct-horse-battery-staple, secure PINs, and bulk generation of up to 50 passwords at once.

Every password gets a live strength meter with entropy in bits and estimated crack time, plus automatic pattern warnings that catch weak spots like sequences and common words. Includes an exclude-confusing-characters option for passwords you'll actually type correctly, and a session history of your last 10 generations. Everything happens locally in your browser — nothing is ever sent to a server.

How to Use

  1. 1Pick a mode: Generator for full control, Speakable, Memorable, Passphrase, PIN, or Bulk
  2. 2In Generator mode, use a Quick Preset (Standard, Strong, Very Strong, Maximum) or drag the length slider from 4 to 64 characters
  3. 3Toggle uppercase, lowercase, numbers and symbols — or turn on "exclude confusing characters" so 0/O and 1/l never appear
  4. 4Add custom exclusions if a website bans certain symbols
  5. 5Click Generate Password and check the strength meter, entropy bits and crack-time estimate
  6. 6Read the pattern warnings — if it spots sequences or common words, regenerate
  7. 7Use the eye icon to hide the password, then hit Copy when ready
  8. 8For accounts you type often, try Memorable or Passphrase mode; for Wi-Fi and shared logins, try Speakable
  9. 9Need many accounts at once? Bulk mode generates up to 50 passwords with one Copy All button

Frequently Asked Questions

Yes — it uses your browser's built-in cryptographic random generator (crypto.getRandomValues), the strongest source of randomness available in a browser. Everything runs locally, so no password ever leaves your device or touches a server.

Length first, then variety. A 16-character password mixing uppercase, lowercase, numbers and symbols is dramatically harder to crack than an 8-character one. The strength meter shows your entropy in bits and estimated crack time so you can see the difference live.

A passphrase is a sequence of random words joined together, like correct-horse-battery-staple. It's long (which means strong) but easy to remember and type — ideal for your main email or password manager master password.

Some characters look identical in many fonts — 0 versus O, or 1 versus l and I. If you'll ever need to type your password by hand (on a TV, a game console, or a phone), excluding them prevents frustrating failed logins.

The tool automatically detects weak patterns: repeated characters, sequences like 123 or abc, famous weak passwords like password and qwerty, and too-short lengths. Passwords with these patterns get cracked first, so regenerate if a warning appears.

6 digits minimum for anything that matters. 4-digit PINs only have 10,000 combinations, which is why the tool warns you when generating shorter ones. Use 4 digits only for low-risk things like a bike lock.

No. Passwords live in your browser's memory only — the History tab keeps your last 10 for the current session and disappears when you close the tab. Nothing is transmitted or saved anywhere.

Yes — Bulk mode creates up to 50 passwords at your chosen length, each with its own copy button plus a Copy All option. Perfect for setting up teams, classrooms, or new accounts.
