Info fields for PyPI

Add comprehensive remote authentication system allowing users to log in from one device by authenticating from another trusted device. Features include:

- Proof of Work (PoW) protection using PBKDF2-SHA512 to prevent abuse
- Simple pairing codes (3 words) protected by dynamic PoW difficulty
- Autocomplete pairing code input with error checking
- Real-time WebSocket communication between devices

Unlike device addition links and reset links with QR codes that only allow adding an authentication method, and that work offline over the duration of several days, this mechanism is strictly online, with 5 minute time limit.

-# PasskeyAuth
+# Paskia
 
-A minimal FastAPI WebAuthn server with WebSocket support for passkey registration. This project demonstrates WebAuthn registration flow with Resident Keys (discoverable credentials) using modern Python tooling.
+An easy to install passkey-based authentication service that protects any web application with strong passwordless login.
 
-## Features
+## What is Paskia?
 
-- 🔐 WebAuthn registration with Resident Keys support
+- Easy to use fully featured auth&auth system (login and permissions)
-- 🔌 WebSocket-based communication for real-time interaction
+- Organization and role-based access control (optional)
-- 🚀 Modern Python packaging with `pyproject.toml`
+   * Org admins control their users and roles
-- 🎨 Clean, responsive HTML interface using @simplewebauthn/browser
+   * Master admin can create multiple independent orgs
-- 📦 No database required - challenges stored locally per connection
+   * Master admin makes permissions available for orgs to assign
-- 🛠️ Development tools: `ruff` for linting and formatting
+- User Profile and Administration by API and web interface.
-- 🧹 Clean architecture with local challenge management
+under `/auth/` or `auth.example.com`
+- Reset tokens and additional device linking via QR code or codewords.
+- Pure Python, FastAPI, packaged with prebuilt Vue frontend
 
-## Docs
+Two interfaces:
+- API fetch: auth checks and login without leaving your app
+- Forward-auth proxy: protect any unprotected site or service (Caddy, Nginx)
 
-- Caddy integration: see `CADDY.md` for short, copy-paste snippets to secure your site with Caddy.
+The API mode is useful for applications that can be customized to run with Paskia. Forward auth can also protect your javascript and other assets. Each provides fine-grained permission control and reauthentication requests where needed, and both can be mixed where needed.
 
-## Requirements
+Single Sign-On (SSO): Users register once and authenticate across all applications under your domain name (configured rp-id).
-
-- Python 3.9+
-- A WebAuthn-compatible authenticator (security key, biometric device, etc.)
 
 ## Quick Start
 
-### Install (editable dev mode)
+Install [UV](https://docs.astral.sh/uv/getting-started/installation/) and run:
 
 ```fish
-uv pip install -e .[dev]
+uvx paskia serve --rp-id example.com
 ```
 
-### Run (new CLI)
+On the first run it downloads the software and prints a registration link for the Admin. If you are going to be connecting `localhost` directly, for testing, leave out the rp-id.
 
-`passkey-auth` now provides subcommands:
+The server will start up on [localhost:4401](http://localhost:4401) "for authentication required", serving for `*.example.com`.
+
+Otherwise you will need a web server such as [Caddy](https://caddyserver.com/) to serve HTTPS on your actual domain names and proxy requests to Paskia and your backend apps.
+
+A quick example without any config file:
+```fish
+sudo caddy reverse-proxy --from example.com --to :4401
+```
+
+For a permanent install of `paskia` CLI command, not needing `uvx`:
+
+```fish
+uv tool install paskia
+```
+
+## Configuration
+
+There is no config file. Pass only the options on CLI:
 
 ```text
-passkey-auth serve [host:port] [--options]
+paskia serve [options]
-passkey-auth dev   [--options]
 ```
 
-Examples (fish shell shown):
+Optional options:
 
-```fish
+- Listen address (one of):
-# Production style (no reload)
+    * `[host]:port`: Address and port (default: `localhost:4401`)
-passkey-auth serve
+    * `unix:/path.sock`: Unix socket
-passkey-auth serve 0.0.0.0:8080 --rp-id example.com --origin https://example.com
+- `--rp-id <domain>`: Main domain (required for production)
+- `--rp-name "<text>"`: Name of your company or site (default: same as rp-id)
+- `--origin <url>`: Explicit single site (default: `https://<rp-id>`)
+- `--auth-host <domain>`: Dedicated authentication site (e.g., `auth.example.com`)
 
-# Development (auto-reload)
+## Documentation
-passkey-auth dev            # localhost:4401
-passkey-auth dev :5500      # localhost on port 5500
-passkey-auth dev 127.0.0.1  # host only, default port 4401
-```
 
-Available options (both subcommands):
+- `API.md`: Complete HTTP and WebSocket API reference
-
+- `Caddy.md`: Caddy configuration examples
-```text
+- `Headers.md`: HTTP headers passed to protected applications
---rp-id <id>        Relying Party ID (default: localhost)
---rp-name <name>    Relying Party name (default: same as rp-id)
---origin <url>      Explicit origin (default: https://<rp-id>)
-```
-
-### Legacy Invocation
-
-If you previously used `python -m passkey.fastapi --dev --host ...`, switch to the new form above. The old flags `--host`, `--port`, and `--dev` are replaced by the `[host:port]` positional and the `dev` subcommand.
-
-## Usage (Web)
-
-1. Start the server with one of the commands above
-2. Open your browser to `http://localhost:4401/auth/` (or your chosen host/port)
-3. Enter a username (or use the default)
-4. Click "Register Passkey"
-5. Follow your authenticator's prompts
-
-Real-time status updates stream over WebSocket.
-
-## Development
-
-### Code Quality
-
-```fish
-# Run linting and formatting with ruff
-uv run ruff check .
-uv run ruff format .
-
-# Or with hatch
-hatch run ruff check .
-hatch run ruff format .
-```
-

-└── README.md

-
-## Technical Details
-
-### WebAuthn Configuration
-
-- **Relying Party ID**: `localhost` (for development)
-- **Resident Keys**: Required (enables discoverable credentials)
-- **User Verification**: Preferred
-- **Supported Algorithms**: ECDSA-SHA256, RSASSA-PKCS1-v1_5-SHA256
-
-### WebSocket Message Flow
-
-1. Client connects to `/ws/{client_id}`
-2. Client sends `registration_challenge` message
-3. Server responds with `registration_challenge_response`
-4. Client completes WebAuthn ceremony and sends `registration_response`
-5. Server verifies and responds with `registration_success` or `error`
-
-### Security Notes
-
-- This is a minimal demo - challenges are stored locally per WebSocket connection
-- For production use, implement proper user storage and session management
-- Consider using Redis or similar for challenge storage in production with multiple server instances
-- Ensure HTTPS in production environments
