+# API Key Authentication and Health Check
+
+## Overview
+
+This implementation adds API key authentication protection to the ComfyUI REST API and a health check endpoint.
+
+## Features
+
+### 1. API Key Authentication
+
+Protects all API endpoints (except exempt ones) with API key authentication.
+
+#### Configuration
+
+You can enable API key authentication in two ways:
+
+**Option 1: Command line argument**
+```bash
+python main.py --api-key "your-secret-api-key-here"
+```
+
+**Option 2: API key file (more secure)**
+```bash
+# Create a file with your API key
+echo "your-secret-api-key-here" > api_key.txt
+
+# Start ComfyUI with the API key file
+python main.py --api-key-file api_key.txt
+```
+
+#### Using the API with Authentication
+
+When API key authentication is enabled, you must provide the API key in your requests:
+
+**Method 1: Authorization Header (Bearer Token)**
+```bash
+curl -H "Authorization: Bearer your-secret-api-key-here" http://localhost:8188/prompt
+```
+
+**Method 2: X-API-Key Header**
+```bash
+curl -H "X-API-Key: your-secret-api-key-here" http://localhost:8188/prompt
+```
+
+**Method 3: Query Parameter (less secure, for testing only)**
+```bash
+curl "http://localhost:8188/prompt?api_key=your-secret-api-key-here"
+```
+
+#### Exempt Endpoints
+
+The following endpoints do NOT require authentication:
+- `/health` - Health check endpoint
+- `/` - Root page (frontend)
+- `/ws` - WebSocket endpoint
+
+### 2. Health Check Endpoint
+
+A new `/health` endpoint provides server status information.
+
+#### Usage
+
+```bash
+curl http://localhost:8188/health
+```
+
+#### Response Format
+
+```json
+{
+  "status": "healthy",
+  "version": "0.4.0",
+  "timestamp": 1702307890.123,
+  "queue": {
+    "pending": 0,
+    "running": 0
+  },
+  "device": "cuda:0",
+  "vram": {
+    "total": 8589934592,
+    "free": 6442450944,
+    "used": 2147483648
+  }
+}
+```
+
+If the server is unhealthy, it returns a 503 status code:
+
+```json
+{
+  "status": "unhealthy",
+  "error": "error message here",
+  "timestamp": 1702307890.123
+}
+```
+
+## Examples
+
+### Starting ComfyUI with API Key Protection
+
+```bash
+# With direct API key
+python main.py --api-key "my-super-secret-key-12345"
+
+# With API key from file
+python main.py --api-key-file /path/to/api_key.txt
+
+# With API key and custom port
+python main.py --api-key "my-key" --port 8080
+```
+
+### Making Authenticated Requests
+
+**Python example:**
+```python
+import requests
+
+API_KEY = "your-api-key-here"
+BASE_URL = "http://localhost:8188"
+
+# Using Authorization header
+headers = {
+    "Authorization": f"Bearer {API_KEY}"
+}
+
+# Check health
+response = requests.get(f"{BASE_URL}/health")
+print(response.json())
+
+# Make authenticated request
+response = requests.post(
+    f"{BASE_URL}/prompt",
+    headers=headers,
+    json={"prompt": {...}}
+)
+print(response.json())
+```
+
+**JavaScript example:**
+```javascript
+const API_KEY = "your-api-key-here";
+const BASE_URL = "http://localhost:8188";
+
+// Using fetch with Authorization header
+async function makeRequest(endpoint, data) {
+  const response = await fetch(`${BASE_URL}${endpoint}`, {
+    method: 'POST',
+    headers: {
+      'Authorization': `Bearer ${API_KEY}`,
+      'Content-Type': 'application/json'
+    },
+    body: JSON.stringify(data)
+  });
+  return response.json();
+}
+
+// Check health (no auth required)
+fetch(`${BASE_URL}/health`)
+  .then(r => r.json())
+  .then(data => console.log(data));
+```
+
+### Monitoring with Health Check
+
+You can use the health endpoint for monitoring and health checks:
+
+```bash
+# Simple health check
+curl http://localhost:8188/health
+
+# Use in a monitoring script
+#!/bin/bash
+response=$(curl -s http://localhost:8188/health)
+status=$(echo $response | jq -r '.status')
+
+if [ "$status" == "healthy" ]; then
+  echo "✓ ComfyUI is healthy"
+  exit 0
+else
+  echo "✗ ComfyUI is unhealthy"
+  exit 1
+fi
+```
+
+## Security Considerations
+
+1. **Keep your API key secret**: Never commit API keys to version control
+2. **Use API key files**: Store API keys in separate files with restricted permissions
+3. **Use HTTPS in production**: Combine with `--tls-keyfile` and `--tls-certfile` options
+4. **Rotate keys regularly**: Change your API key periodically
+5. **Use strong keys**: Generate long, random API keys (e.g., using `openssl rand -hex 32`)
+
+### Generating a Secure API Key
+
+```bash
+# Generate a secure random API key
+openssl rand -hex 32
+
+# Or using Python
+python -c "import secrets; print(secrets.token_hex(32))"
+```
+
+## Troubleshooting
+
+### 401 Unauthorized Error
+
+If you receive a 401 error:
+- Verify the API key is correct
+- Check that you're including the key in the correct header format
+- Ensure there are no extra spaces or newlines in the key
+
+### Health Check Returns 503
+
+If the health check returns 503:
+- Check the server logs for error details
+- Verify ComfyUI started correctly
+- Check system resources (memory, disk space)
+
+## Disabling Authentication
+
+To disable API key authentication, simply don't provide the `--api-key` or `--api-key-file` arguments when starting ComfyUI. The server will work exactly as before with no authentication required.

+# ComfyUI API Authentication Guide
+
+## Overview
+
+ComfyUI now supports API key authentication to protect your REST API endpoints. This guide covers setup, usage, and logout procedures.
+
+## Features
+
+- **API Key Authentication**: Protect all API endpoints with a simple API key
+- **Multiple Auth Methods**: Bearer token, X-API-Key header, or query parameter
+- **Health Endpoint**: Monitor server status without authentication
+- **Frontend Login**: Built-in login page for browser access
+- **Session Management**: Remember API key across sessions or per-session only
+
+## Quick Start
+
+### 1. Start Server with API Key
+
+```bash
+# Using command line argument
+python3 main.py --api-key "your-secure-api-key-here"
+
+# Or using a file (recommended for production)
+echo "your-secure-api-key-here" > api_key.txt
+python3 main.py --api-key-file api_key.txt
+```
+
+### 2. Access ComfyUI
+
+When you navigate to `http://127.0.0.1:8188`, you'll be redirected to a login page.
+
+### 3. Login
+
+1. Enter your API key in the password field
+2. Optionally check "Remember me" to persist the key across browser sessions
+3. Click "Login"
+
+The system validates your key against the `/health` endpoint before storing it.
+
+### 4. Logout
+
+To logout, visit:
+```
+http://127.0.0.1:8188/auth_login.html?logout=true
+```
+
+This will clear your stored API key and redirect you to the login page.
+
+## API Usage
+
+### Authentication Methods
+
+You can authenticate API requests in three ways:
+
+#### 1. Bearer Token (Recommended)
+```bash
+curl -H "Authorization: Bearer your-api-key" http://127.0.0.1:8188/prompt
+```
+
+#### 2. X-API-Key Header
+```bash
+curl -H "X-API-Key: your-api-key" http://127.0.0.1:8188/prompt
+```
+
+#### 3. Query Parameter
+```bash
+curl "http://127.0.0.1:8188/prompt?api_key=your-api-key"
+```
+
+### Python Example
+
+```python
+import requests
+
+API_KEY = "your-api-key"
+BASE_URL = "http://127.0.0.1:8188"
+
+# Using Bearer token
+headers = {"Authorization": f"Bearer {API_KEY}"}
+response = requests.get(f"{BASE_URL}/queue", headers=headers)
+
+# Using X-API-Key header
+headers = {"X-API-Key": API_KEY}
+response = requests.get(f"{BASE_URL}/queue", headers=headers)
+
+# Using query parameter
+response = requests.get(f"{BASE_URL}/queue?api_key={API_KEY}")
+```
+
+### JavaScript Example
+
+```javascript
+const API_KEY = "your-api-key";
+const BASE_URL = "http://127.0.0.1:8188";
+
+// Using Bearer token
+fetch(`${BASE_URL}/queue`, {
+    headers: {
+        "Authorization": `Bearer ${API_KEY}`
+    }
+})
+.then(response => response.json())
+.then(data => console.log(data));
+```
+
+## Health Endpoint
+
+The `/health` endpoint is always accessible without authentication:
+
+```bash
+curl http://127.0.0.1:8188/health
+```
+
+Response includes:
+- Server status
+- Queue information (pending/running tasks)
+- Device information (GPU/CPU)
+- VRAM statistics
+
+Example response:
+```json
+{
+  "status": "ok",
+  "queue": {
+    "pending": 0,
+    "running": 0
+  },
+  "device": {
+    "name": "mps",
+    "type": "mps"
+  },
+  "vram": {
+    "total": 68719476736,
+    "free": 68719476736
+  }
+}
+```
+
+## Exempt Endpoints
+
+The following paths are exempt from authentication:
+
+### Static Files
+- `.html`, `.js`, `.css`, `.json` files
+- `.png`, `.jpg`, `.jpeg`, `.gif`, `.webp` images
+- `.svg`, `.ico` icons
+- `.woff`, `.woff2`, `.ttf` fonts
+- `.mp3`, `.wav` audio files
+- `.mp4`, `.webm` video files
+
+### API Paths
+- `/` - Root path (serves login if not authenticated)
+- `/health` - Health check endpoint
+- `/ws` - WebSocket endpoint
+- `/auth_login.html` - Login page
+- `/auth_inject.js` - Auth injection script
+- `/extensions/*` - Extension files
+- `/templates/*` - Template files
+- `/docs/*` - Documentation
+
+## Security Best Practices
+
+1. **Use Strong API Keys**: Generate random, long API keys (32+ characters)
+   ```bash
+   # Generate secure API key on macOS/Linux
+   openssl rand -base64 32
+   ```
+
+2. **Use API Key Files**: Store keys in files rather than command line
+   ```bash
+   python3 main.py --api-key-file /secure/path/api_key.txt
+   ```
+
+3. **File Permissions**: Restrict key file access
+   ```bash
+   chmod 600 api_key.txt
+   ```
+
+4. **HTTPS**: Use reverse proxy with SSL in production
+   ```nginx
+   server {
+       listen 443 ssl;
+       server_name your-domain.com;
+       
+       ssl_certificate /path/to/cert.pem;
+       ssl_certificate_key /path/to/key.pem;
+       
+       location / {
+           proxy_pass http://127.0.0.1:8188;
+           proxy_set_header Host $host;
+           proxy_set_header X-Real-IP $remote_addr;
+       }
+   }
+   ```
+
+5. **Environment Variables**: Store keys in environment
+   ```bash
+   export COMFYUI_API_KEY=$(cat api_key.txt)
+   python3 main.py --api-key "$COMFYUI_API_KEY"
+   ```
+
+## Frontend Integration
+
+The authentication system automatically handles frontend requests:
+
+1. When authentication is enabled, `auth_inject.js` is injected into `index.html`
+2. This script intercepts all `fetch()` and `XMLHttpRequest` calls
+3. Authorization headers are added automatically to all requests
+4. On 401 responses, the user is redirected to the login page
+
+### Session Storage
+
+- **localStorage**: API key persists across browser sessions (when "Remember me" is checked)
+- **sessionStorage**: API key cleared when browser/tab closes (when "Remember me" is not checked)
+
+## Troubleshooting
+
+### 401 Unauthorized Errors
+
+1. Verify API key matches server configuration
+2. Check authentication header format
+3. Ensure endpoint isn't expecting different auth method
+
+### Login Page Not Appearing
+
+1. Clear browser cache
+2. Verify `auth_login.html` and `auth_inject.js` exist in ComfyUI root
+3. Check server logs for errors
+
+### WebSocket Connection Issues
+
+WebSocket connections (`/ws`) are exempt from authentication, but may require authentication for initial HTTP upgrade depending on your setup.
+
+### Logout Not Working
+
+Visit the logout URL directly:
+```
+http://127.0.0.1:8188/auth_login.html?logout=true
+```
+
+Or clear storage manually in browser DevTools:
+```javascript
+localStorage.removeItem('comfyui_api_key');
+sessionStorage.removeItem('comfyui_api_key');
+```
+
+## Disabling Authentication
+
+To disable authentication, simply start the server without the `--api-key` or `--api-key-file` arguments:
+
+```bash
+python3 main.py
+```
+
+## Migration from Unauthenticated Setup
+
+If you're adding authentication to an existing ComfyUI installation:
+
+1. Ensure `auth_login.html` and `auth_inject.js` exist in root directory
+2. Update `server.py` with authentication routes
+3. Add `middleware/auth_middleware.py`
+4. Update `comfy/cli_args.py` with API key arguments
+5. Restart server with `--api-key` argument
+6. Update API clients to include authentication
+
+## Support
+
+For issues or questions:
+- Check server logs for authentication errors
+- Verify middleware is properly configured
+- Test with `/health` endpoint first (no auth required)
+- Review `middleware/auth_middleware.py` for exempt paths

+# ComfyUI Frontend Authentication Guide
+
+## Overview
+
+When API key authentication is enabled, the ComfyUI frontend will automatically require users to log in with the API key before accessing the interface.
+
+## How It Works
+
+1. **Automatic Redirection**: When you access ComfyUI with authentication enabled, you'll be automatically redirected to a login page if no valid API key is stored.
+
+2. **API Key Storage**: After successful login, your API key is stored in your browser (localStorage or sessionStorage) depending on your "Remember me" choice.
+
+3. **Automatic Injection**: The API key is automatically added to all API requests via the `Authorization: Bearer <key>` header.
+
+4. **Session Management**: 
+   - **Remember me (checked)**: API key stored in localStorage (persists across browser sessions)
+   - **Remember me (unchecked)**: API key stored in sessionStorage (cleared when browser closes)
+
+## Using the Frontend with Authentication
+
+### First Time Access
+
+1. Start ComfyUI with an API key:
+   ```bash
+   python main.py --api-key "your-secret-key-123"
+   ```
+
+2. Open your browser and navigate to `http://localhost:8188`
+
+3. You'll be presented with a login page
+
+4. Enter your API key and click "Login"
+
+5. Choose whether to remember your login (recommended for personal devices only)
+
+### Login Page Features
+
+- **Show API Key**: Toggle to view the key you're entering
+- **Remember Me**: Keep your session active across browser restarts
+- **Auto-validation**: The system validates your key before storing it
+
+### Logging Out
+
+To log out and clear your stored API key:
+
+**Option 1: JavaScript Console**
+```javascript
+comfyuiLogout()
+```
+
+**Option 2: Browser DevTools**
+1. Open DevTools (F12)
+2. Go to Application > Storage
+3. Clear localStorage and sessionStorage
+4. Refresh the page
+
+**Option 3: Manual URL**
+Navigate to: `http://localhost:8188/auth_login.html`
+
+### Security Considerations
+
+#### For Personal Use
+- ✅ Enable "Remember me" for convenience
+- ✅ Use strong, unique API keys
+- ✅ Keep your browser updated
+
+#### For Shared/Public Computers
+- ❌ **DO NOT** enable "Remember me"
+- ✅ Always log out when finished
+- ✅ Clear browser data after use
+- ✅ Consider using a private/incognito window
+
+#### For Production Deployments
+- ✅ Always use HTTPS (combine with `--tls-keyfile` and `--tls-certfile`)
+- ✅ Use strong, randomly generated API keys
+- ✅ Rotate keys regularly
+- ✅ Monitor access logs for unauthorized attempts
+- ✅ Consider using additional security layers (VPN, firewall, etc.)
+
+## Troubleshooting
+
+### "Invalid API Key" Error
+
+**Problem**: Login fails with invalid API key message
+
+**Solutions**:
+1. Verify you're using the correct API key
+2. Check for extra spaces or newlines
+3. Ensure the server was started with the same API key
+4. Check server logs for authentication attempts
+
+### Automatic Logout
+
+**Problem**: Frequently logged out automatically
+
+**Possible Causes**:
+1. API key changed on server (restart required)
+2. Browser cleared storage automatically
+3. "Remember me" was not checked
+4. Session expired (if using sessionStorage)
+
+**Solution**: Check "Remember me" when logging in
+
+### Login Page Not Showing
+
+**Problem**: Can't access login page
+
+**Possible Causes**:
+1. Authentication not enabled (no `--api-key` argument)
+2. Browser cached old version
+
+**Solution**:
+1. Hard refresh the page (Ctrl+Shift+R or Cmd+Shift+R)
+2. Clear browser cache
+3. Try accessing directly: `http://localhost:8188/auth_login.html`
+
+### API Requests Still Failing
+
+**Problem**: Some API requests return 401 after login
+
+**Solutions**:
+1. Check browser console for errors
+2. Verify API key is stored: Open DevTools > Application > Storage
+3. Try logging out and back in
+4. Clear all browser data and try again
+
+## Advanced Usage
+
+### Programmatic Access with Frontend
+
+If you need to access the API programmatically while using the frontend:
+
+```javascript
+// Get the stored API key
+const apiKey = localStorage.getItem('comfyui_api_key') || 
+               sessionStorage.getItem('comfyui_api_key');
+
+// Make authenticated requests
+fetch('/api/system_stats', {
+    headers: {
+        'Authorization': `Bearer ${apiKey}`
+    }
+}).then(r => r.json()).then(console.log);
+```
+
+### Custom Frontend Integration
+
+If you're building a custom frontend, you can use the same mechanism:
+
+1. **Login Flow**:
+   ```javascript
+   // Validate API key
+   const response = await fetch('/health', {
+       headers: {
+           'Authorization': `Bearer ${apiKey}`
+       }
+   });
+   
+   if (response.ok) {
+       // Store the key
+       localStorage.setItem('comfyui_api_key', apiKey);
+   }
+   ```
+
+2. **Request Interceptor**:
+   ```javascript
+   // Add to all requests
+   const apiKey = localStorage.getItem('comfyui_api_key');
+   
+   fetch(url, {
+       headers: {
+           'Authorization': `Bearer ${apiKey}`,
+           ...otherHeaders
+       }
+   });
+   ```
+
+3. **Handle 401 Responses**:

+
+## API Endpoints Reference
+
+### Public Endpoints (No Authentication Required)
+- `GET /` - Main page (with auth script injected)
+- `GET /health` - Health check
+- `GET /auth_login.html` - Login page
+- `GET /auth_inject.js` - Auth injection script
+- `GET /ws` - WebSocket connection
+- Static files (`.js`, `.css`, `.html`, etc.)
+
+### Protected Endpoints (Authentication Required)
+- All `/api/*` endpoints
+- All `/internal/*` endpoints
+- Most other API endpoints
+
+## Browser Compatibility
+
+The authentication system works with all modern browsers:
+- ✅ Chrome/Edge 90+
+- ✅ Firefox 88+
+- ✅ Safari 14+
+- ✅ Opera 76+
+
+## FAQs
+
+**Q: Can I use ComfyUI without authentication?**  
+A: Yes! Simply start ComfyUI without the `--api-key` argument.
+
+**Q: Can I change the API key without losing my workflows?**  
+A: Yes, workflows are stored separately. Just update the key on the server and re-login.
+
+**Q: Is my API key secure?**  
+A: The key is stored in browser storage and sent over HTTPS (if configured). For maximum security, use HTTPS and strong keys.
+
+**Q: Can multiple users use different API keys?**  
+A: Currently, the system supports a single API key. For multi-user scenarios, each user must use the same key.
+
+**Q: What happens if I forget my API key?**  
+A: Check your server startup command or the file specified in `--api-key-file`.
+
+## Support
+
+For issues or questions:
+1. Check the server logs
+2. Review browser console for errors
+3. Refer to the main authentication documentation: `API_AUTHENTICATION.md`
+4. Check the quick start guide: `QUICK_START_AUTH.md`

+# Quick Start Guide - API Authentication
+
+## Step-by-Step Instructions
+
+### 1. Start ComfyUI with API Key
+
+```bash
+# Stop any running ComfyUI instance first
+# Then start with an API key:
+
+python main.py --api-key "my-secret-key-123"
+```
+
+**You should see in the logs:**
+```
+[Auth] API Key authentication enabled
+```
+
+### 2. Test the Authentication
+
+**Health check (works without auth):**
+```bash
+curl http://localhost:8188/health
+```
+
+**Protected endpoint without auth (should fail):**
+```bash
+curl http://localhost:8188/object_info
+# Should return: {"error": "Unauthorized", "message": "..."}
+```
+
+**Protected endpoint with auth (should work):**
+```bash
+curl -H "Authorization: Bearer my-secret-key-123" http://localhost:8188/object_info
+# Should return: {...node definitions...}
+```
+
+### 3. Run the Test Script
+
+```bash
+chmod +x test_auth_quick.sh
+./test_auth_quick.sh
+```
+
+## Common Issues
+
+### Issue: All requests work without authentication
+
+**Problem:** You didn't start the server with `--api-key`
+
+**Solution:**
+```bash
+# Stop the server (Ctrl+C)
+# Restart with API key:
+python main.py --api-key "your-key-here"
+```
+
+**Verify it's enabled:**
+```bash
+# In another terminal, check if auth is working:
+curl http://localhost:8188/object_info
+# Should return 401 Unauthorized
+```
+
+### Issue: Authentication is enabled but I get 401 even with correct key
+
+**Problem:** Key format or typo
+
+**Solution:**
+- Ensure no extra spaces in the key
+- Check the Authorization header format: `Authorization: Bearer YOUR_KEY`
+- Try X-API-Key header: `X-API-Key: YOUR_KEY`
+
+## Example: Full Workflow
+
+```bash
+# 1. Generate a secure key
+python -c "import secrets; print(secrets.token_hex(32))"
+# Output: a1b2c3d4e5f6...
+
+# 2. Save to file
+echo "a1b2c3d4e5f6..." > api_key.txt
+
+# 3. Start server with key file
+python main.py --api-key-file api_key.txt
+
+# 4. Use the API
+API_KEY=$(cat api_key.txt)
+curl -H "Authorization: Bearer $API_KEY" http://localhost:8188/object_info
+```
+
+## Test with Python
+
+```python
+import requests
+
+API_KEY = "my-secret-key-123"
+BASE_URL = "http://localhost:8188"
+
+# This should fail (no auth)
+response = requests.get(f"{BASE_URL}/object_info")
+print(f"No auth: {response.status_code}")  # Should be 401
+
+# This should work (with auth)
+headers = {"Authorization": f"Bearer {API_KEY}"}
+response = requests.get(f"{BASE_URL}/object_info", headers=headers)
+print(f"With auth: {response.status_code}")  # Should be 200
+```
+
+## Disable Authentication
+
+Simply start ComfyUI without the `--api-key` argument:
+
+```bash
+python main.py
+```
+
+The server will work exactly as before with no authentication required.
