A Chrome/Firefox extension that remembers which Google Account you used for specific services and highlights it during login.

What It Does

When signing into third-party services through Google OAuth, AuthMemory:

• Detects which service you're logging into
• Remembers which Google account you used
• Highlights that account next time with a visual badge

No more guessing which account you used for Replit, Vercel, or any other service!

Installation

Chrome

1. Download the latest auth-memory-chrome-v*.zip from releases
2. Extract the zip file
3. Open chrome://extensions
4. Enable "Developer mode"
5. Click "Load unpacked" and select the extracted folder

Firefox

1. Download the latest auth-memory-firefox-v*.zip from releases
2. Open about:debugging#/runtime/this-firefox
3. Click "Load Temporary Add-on"
4. Select the zip file

Development

# Install dependencies
npm install

# Build browser packages
npm run build

# Create a release (bump version, build, tag, and push)
npm run release

How It Works

The extension runs on accounts.google.com and:

1. Extracts the destination service from OAuth URL parameters
2. Stores a mapping of domain → email when you select an account
3. Highlights the previously used account for that domain on future visits
