+# Forward Authentication
+
+## Overview
+
+Forward authentication allows a reverse proxy (like Caddy, Nginx, Traefik) to delegate authentication decisions to a separate service. Clinch implements this pattern to provide SSO for multiple applications.
+
+## Key Implementation Details
+
+### Tip 1: Forward URL Configuration ✅
+
+Clinch includes the original destination URL in the redirect parameters:
+
+```ruby
+login_params = {
+  rd: original_url,    # redirect destination
+  rm: request.method   # request method
+}
+login_url = "#{base_url}/signin?#{login_params.to_query}"
+```
+
+Example: `https://clinch.example.com/signin?rd=https://metube.example.com/&rm=GET`
+
+### Tip 2: Root Domain Cookies ✅
+
+Clinch sets authentication cookies on the root domain to enable cross-subdomain authentication:
+
+```ruby
+def extract_root_domain(host)
+  # clinch.example.com -> .example.com
+  # app.example.co.uk -> .example.co.uk
+  # localhost -> nil (no domain restriction)
+end
+
+cookies.signed.permanent[:session_id] = {
+  value: session.id,
+  httponly: true,
+  same_site: :lax,
+  secure: Rails.env.production?,
+  domain: ".example.com"  # Available to all subdomains
+}
+```
+
+This allows the same session cookie to work across:
+- `clinch.example.com` (auth service)
+- `metube.example.com` (protected app)
+- `sonarr.example.com` (protected app)
+
+### Tip 3: Race Condition Solution with One-Time Tokens ✅
+
+**Problem**: After successful authentication, there's a race condition where the browser immediately follows the redirect to the protected application, but the reverse proxy makes a forward auth request before the browser has processed and started sending the new session cookie.
+
+**Solution**: Clinch uses a one-time token system to bridge this timing gap:
+
+```ruby
+# During authentication (authentication.rb)
+def create_forward_auth_token(session_obj)
+  token = SecureRandom.urlsafe_base64(32)
+
+  # Store token for 30 seconds
+  Rails.cache.write("forward_auth_token:#{token}", session_obj.id, expires_in: 30.seconds)
+
+  # Add token to redirect URL
+  if session[:return_to_after_authenticating].present?
+    original_url = session[:return_to_after_authenticating]
+    uri = URI.parse(original_url)
+    query_params = URI.decode_www_form(uri.query || "").to_h
+    query_params['fa_token'] = token
+    uri.query = URI.encode_www_form(query_params)
+    session[:return_to_after_authenticating] = uri.to_s
+  end
+end
+```
+
+```ruby
+# In forward auth verification (forward_auth_controller.rb)
+def check_forward_auth_token
+  token = params[:fa_token]
+  return nil unless token.present?
+
+  session_id = Rails.cache.read("forward_auth_token:#{token}")
+  return nil unless session_id
+
+  session = Session.find_by(id: session_id)
+  return nil unless session && !session.expired?
+
+  # Delete token immediately (one-time use)
+  Rails.cache.delete("forward_auth_token:#{token}")
+
+  Rails.logger.info "ForwardAuth: Valid one-time token used for session #{session_id}"
+  session_id
+end
+```
+
+**How it works:**
+1. User authenticates → Rails sets session cookie + generates one-time token
+2. Token gets appended to redirect URL: `https://metube.example.com/?fa_token=abc123...`
+3. Browser follows redirect → Caddy makes forward auth request with token
+4. Forward auth validates token → authenticates user immediately
+5. Token is deleted (one-time use) → subsequent requests use normal cookies
+
+**Security Features:**
+- Tokens expire after 30 seconds
+- One-time use (deleted after validation)
+- Secure random generation
+- Session validation before token acceptance
+
+## Authelia Analysis
+
+### Implementation Comparison
+
+**Authelia Approach (from analysis of `tmp/authelia/`):**
+- Returns `302 Found` or `303 See Other` with `Location` header
+- Direct browser redirects (bypasses some proxy logic)
+- Uses StatusFound (302) or StatusSeeOther (303)
+
+**Clinch Current Implementation:**
+- Returns `302 Found` directly to login URL (matching Authelia)
+- Includes `rd` (redirect destination) and `rm` (request method) parameters
+- Uses root domain cookies for cross-subdomain authentication
+
+## How Clinch Forward Auth Works
+
+### Authentication Flow
+
+1. **User visits** `https://metube.example.com/`
+2. **Caddy forwards** to `http://clinch:9000/api/verify?rd=https://clinch.example.com`
+3. **Clinch checks session**:
+   - **If authenticated**: Returns `200 OK` with user headers
+   - **If not authenticated**: Returns `302 Found` to login URL with redirect parameters
+4. **Browser follows redirect** to Clinch login page
+5. **User logs in** (with TOTP if enabled):
+   - Rails creates session and sets cross-domain cookie
+   - **Rails generates one-time token** and appends to redirect URL
+   - User is redirected to: `https://metube.example.com/?fa_token=abc123...`
+6. **Browser follows redirect** → Caddy makes forward auth request with token
+7. **Clinch validates one-time token** → authenticates user immediately
+8. **Token is deleted** → subsequent requests use normal session cookies
+9. **Caddy forwards to MEtube** with proper authentication headers
+
+### Response Headers
+
+**Successful Authentication (200 OK):**
+```
+Remote-User: user@example.com
+Remote-Email: user@example.com
+Remote-Groups: media-managers,users
+Remote-Admin: false
+```
+
+**Redirect to Login (302 Found):**
+```
+Location: https://clinch.example.com/signin?rd=https://metube.example.com/&rm=GET
+```
+
+## Caddy Configuration
+
+```caddyfile
+# Clinch SSO (main authentication server)
+clinch.example.com {
+    reverse_proxy clinch:9000
+}
+
+# MEtube (protected by Clinch)
+metube.example.com {
+    forward_auth clinch:9000 {
+        uri /api/verify?rd=https://clinch.example.com
+        copy_headers Remote-User Remote-Email Remote-Groups Remote-Admin
+    }
+
+    handle {
+        reverse_proxy * {
+            to http://192.168.2.223:8081
+            header_up X-Real-IP {remote_host}
+        }
+    }
+}
+```
+
+## Key Files
+
+- **Forward Auth Controller**: `app/controllers/api/forward_auth_controller.rb`
+- **Authentication Logic**: `app/controllers/concerns/authentication.rb`
+- **Caddy Examples**: `docs/caddy-example.md`
+- **Authelia Analysis**: `docs/authelia-forward-auth.md`
+
+## Testing
+
+```bash
+# Test forward auth endpoint directly
+curl -v http://localhost:9000/api/verify?rd=https://clinch.example.com
+
+# Should return 302 redirect to login page
+# Or 200 OK if you have a valid session cookie
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Authentication Loop**: Check that cookies are set on the root domain
+2. **Session Not Shared**: Verify `extract_root_domain` is working correctly
+3. **Caddy Connection**: Ensure `clinch:9000` resolves from your Caddy container
+4. **Race Condition After Authentication**:
+   - **Problem**: Forward auth fails immediately after login due to cookie timing
+   - **Solution**: One-time tokens automatically bridge this gap
+   - **Debug**: Look for "ForwardAuth: Valid one-time token used" in logs
+
+### Debug Logging
+
+Enable debug logging in `forward_auth_controller.rb` to see:
+- Headers received from Caddy
+- Domain extraction results
+- Redirect URLs being generated
+- Token validation during race condition resolution
+
+```ruby
+Rails.logger.info "ForwardAuth Headers: Host=#{host}, X-Forwarded-Host=#{original_host}"
+Rails.logger.info "Setting 302 redirect to: #{login_url}"
+Rails.logger.info "ForwardAuth: Valid one-time token used for session #{session_id}"
+Rails.logger.info "Authentication: Added forward auth token to redirect URL: #{url}"
+```
+
+**Key log messages to watch for:**
+- `"Authentication: Added forward auth token to redirect URL"` - Token generation during login
+- `"ForwardAuth: Valid one-time token used for session X"` - Successful race condition resolution
+- `"ForwardAuth: Session cookie present: false"` - Cookie timing issue (should be resolved by token)
