domain-key

Automatically generate a strong and unique password from domain + your seed.

How It Works

The script concatenates main domain part + your secret seed, hashes with SHA-384, then generates a 12-character password containing uppercase, lowercase, digits, and special characters using rejection sampling and Fisher-Yates shuffle. Same website + same seed = same password — no memorization or storage required.

Installation

Install Tampermonkey or Violentmonkey browser extension
Click install link or manually add domain-key.user.js content to your script manager
Enable the script and visit any website to start using

Usage

Basic Usage

Visit any website's registration/login page
Focus on a password input field — a 🔑 button appears on the right
Click the button → password is automatically filled and copied to clipboard

First Time Use

Clicking the 🔑 button opens a seed setup dialog. Enter at least 6 characters for your secret seed. You can also modify it anytime via Tampermonkey menu → "设置密码种子" (Set Password Seed).

Account Suffix

Shift + click the 🔑 button to open the suffix input dialog. Add modifiers (like work, personal) for different accounts on the same domain, and the script will generate different passwords.
