Key Features

Cryptographically Secure

Passwords use the Web Crypto random generator with unbiased sampling — not Math.random.

Fully Customizable

Set length from 4 to 128 and toggle uppercase, lowercase, numbers, and symbols.

Live Strength Meter

See real-time entropy in bits and a strength rating as you adjust options.

Never Uploaded

Every password is generated locally and is never transmitted or stored.

About This Tool

What is the Password Generator?

The Password Generator creates strong, random passwords entirely in your browser. You control the length and which character types are included, and a live meter shows the resulting entropy so you can judge how hard the password is to crack.

Common Uses

  • New account sign-ups: Generate a unique password for every service.
  • Rotating credentials: Quickly replace a leaked or reused password.
  • Wi-Fi and device keys: Create long, random keys for routers and IoT.
  • API tokens and secrets: Produce high-entropy strings for configs.

Privacy-First by Design

Passwords are generated with the Web Crypto API and stay on your device. Nothing is sent to a server, logged, or cached remotely — the tool works offline once the page has loaded.

FAQ

Length and randomness. A longer password drawn from a larger character set has more entropy, which makes it exponentially harder to guess or brute-force. Aim for 16+ characters with mixed types.
Yes. Passwords are created with the browser's cryptographically secure random generator and never leave your device — nothing is sent over the network.
No. All processing happens entirely in your browser. Your data never leaves your device — nothing is uploaded to any server.
Yes. Once the page has loaded, the tool works completely offline. For the best experience, install PrivaDeck as a PWA from your browser.
