SuperGenPass Extension

Generate deterministic passwords using the SuperGenPass algorithm. Create unique, strong passwords for websites based on a master password and domain.

Features

  • Generate passwords using the official SuperGenPass algorithm
  • Support for MD5 and SHA-512 hashing methods
  • Configurable password length (4-24 characters)
  • Automatic subdomain removal for consistent passwords
  • Optional secret password for additional security
  • Copy generated passwords to clipboard

How it works

SuperGenPass creates unique passwords for each website by hashing your master password combined with the website's domain. This means:

  • Same master password + same domain = same generated password
  • Different domains get different passwords
  • No passwords are stored - they're generated on-demand

Setup

  1. Install the extension
  2. Set your master password in the extension preferences
  3. Configure other options as needed (length, hash method, etc.)

Usage

  1. Open the SuperGenPass command
  2. Enter a domain name (e.g., example.com) or full URL
  3. Click "Generate Password"
  4. Copy the generated password to use on the website

Security Notes

  • Keep your master password secure and memorable
  • The generated passwords are deterministic - if you forget one, you can regenerate it
  • Never share your master password
  • Consider using a secret password for additional security layers

Algorithm Details

The SuperGenPass algorithm:

  1. Combines master password + optional secret + ":" + domain
  2. Hashes the result using MD5 (default) or SHA-512
  3. Ensures the final password meets complexity requirements (starts with lowercase, contains uppercase and numbers)
  4. Returns the first N characters as specified
