+# Website Login Implementation
+
+## Overview
+This implementation adds login functionality to the website that authenticates users against the panel's database (ogp_users table) while maintaining separate sessions for the website and panel.
+
+## Files Created/Modified
+
+### 1. `_website/login.php` (NEW)
+- Full-featured login page with modern UI
+- Authenticates against panel DB using MD5 password hashing (panel-compatible)
+- Creates separate website session using `gameservers_website` session name
+- Logs all login attempts via logger() function
+- Session variables set:
+  - `$_SESSION['website_user_id']` - User ID from ogp_users
+  - `$_SESSION['website_username']` - Username
+  - `$_SESSION['website_user_role']` - User role (admin, user, etc.)
+  - `$_SESSION['website_user_email']` - User email
+  - `$_SESSION['website_login_time']` - Timestamp of login
+
+### 2. `_website/logout.php` (NEW)
+- Cleanly destroys website session
+- Logs logout events
+- Redirects to homepage after logout
+- Properly clears session cookies
+
+### 3. `_website/index.php` (MODIFIED)
+- Added session management at the top
+- Added header with Login/Logout button and user greeting
+- Shows "Welcome, [username]!" when logged in
+- Maintains same visual design with added header
+
+## Session Management
+
+### Separate Sessions
+- **Website Session**: `gameservers_website` (this implementation)
+- **Panel Session**: `opengamepanel_web` (existing panel)
+
+These sessions are completely separate - users can be logged into one without being logged into the other.
+
+## Security Features
+
+1. **SQL Injection Prevention**: Uses `mysqli_real_escape_string()` for input sanitization
+2. **Password Hashing**: Compatible with panel's MD5 hashing (legacy but matches panel)
+3. **Session Isolation**: Separate session name prevents conflicts with panel
+4. **XSS Prevention**: Uses `htmlspecialchars()` for output escaping
+5. **Logging**: All login/logout events are logged via logger() function
+
+## Database Requirements
+
+Requires connection to panel database with access to:
+- `ogp_users` table (fields: user_id, users_login, users_passwd, users_role, users_email)
+- Connection configured in `db.php`
+
+## Usage
+
+### For Users:
+1. Visit `_website/login.php` to login
+2. Enter panel credentials (username/password)
+3. After successful login, redirected to homepage with session active
+4. Click "Logout" button to end session
+
+### For Developers:
+Check if user is logged in:
+```php
+session_name("gameservers_website");
+session_start();
+
+if (isset($_SESSION['website_user_id']) && !empty($_SESSION['website_user_id'])) {
+    // User is logged in
+    $username = $_SESSION['website_username'];
+    $user_id = $_SESSION['website_user_id'];
+    $user_role = $_SESSION['website_user_role'];
+}
+```
+
+## Future Enhancements (Optional)
+
+1. **Password Hashing Upgrade**: Implement modern bcrypt/argon2 with transparent upgrade on login
+2. **CSRF Protection**: Add CSRF tokens to login form
+3. **Rate Limiting**: Add IP-based login attempt limiting (similar to panel's ban_list)
+4. **Remember Me**: Add persistent login cookie option
+5. **Password Reset**: Integrate with panel's password reset flow
+6. **Two-Factor Auth**: Optional 2FA for enhanced security
+
+## Testing
+
+All files pass PHP syntax validation:
+```bash
+php -l _website/index.php
+php -l _website/login.php
+php -l _website/logout.php
+```
+
+## Alignment with Copilot Instructions
+
+This implementation follows the no-code planning guidelines from `.github/copilot-instructions.md`:
+
+✅ Website uses panel DB for authentication  
+✅ Sessions remain separate (website ≠ panel)  
+✅ Auth compatibility maintained (MD5 hash for panel users)  
+✅ Minimal changes to existing code  
+✅ Repository-first approach (reused existing db.php, logger function)  
+✅ Security considerations (SQL injection prevention, session isolation)  
+
+## Notes
+
+- Login credentials are the same as panel login (same user table)
+- Website session does not grant access to panel - separate login required
+- Logger function from db.php creates logfile.txt for audit trail
