+Blueprint Migration Status - 20250616_223724
+==========================================
+
+Blueprints erstellt und registriert:
+- auth_bp (9 routes) - Authentication
+- admin_bp (10 routes) - Admin Dashboard
+- license_bp (4 routes) - License Management
+- customer_bp (7 routes) - Customer Management
+- resource_bp (7 routes) - Resource Pool
+- session_bp (6 routes) - Session Management
+- batch_bp (4 routes) - Batch Operations
+- api_bp (14 routes) - API Endpoints
+- export_bp (5 routes) - Export Functions
+
+Gesamt: 66 Routes in Blueprints
+
+Status:
+- Alle Routes aus app.py sind auskommentiert
+- Blueprints sind aktiv und funktionsfähig
+- Keine aktiven @app.route mehr in app.py
+
+Nächste Schritte:
+1. Auskommentierte Routes entfernen
+2. Redundante Funktionen bereinigen
+3. URL-Präfixe implementieren

+Sicherheitshinweise:
+-------------------
+✓ Bewahren Sie diese Codes getrennt von Ihrem Passwort auf
+✓ Speichern Sie sie an einem sicheren physischen Ort
+✓ Teilen Sie diese Codes niemals mit anderen
+✓ Jeder Code funktioniert nur einmal
+
+Bei Verlust Ihrer Authenticator-App:
+------------------------------------
+1. Gehen Sie zur Login-Seite
+2. Geben Sie Benutzername und Passwort ein
+3. Klicken Sie auf "Backup-Code verwenden"
+4. Geben Sie einen dieser Codes ein
+
+Nach Verwendung eines Codes sollten Sie neue Backup-Codes generieren.`;
