Secure, temporary access to SIMATIC HMI Unified Comfort Panels using Access Keys
SIMATIC Unified Air 3.0 introduces Access Key Authentication, redefining secure and flexible access to SIMATIC HMI Unified Comfort Panels for modern industrial service scenarios.
Secure access without accounts or passwords
Access Key Authentication enables temporary, time-limited access to panels without creating user accounts, registering mobile devices, or sharing passwords. Engineers generate cryptographically signed Access Keys that grant precisely defined access and expire automatically.
Built for service and maintenance
Unified Air 3.0 is designed for environments with external technicians, contractors, and rotating service teams. Access is delivered quickly, securely, and entirely offline via Bluetooth.
Key features
• Token-based Access Key authentication
• No UMC user accounts required for service staff
• No mobile device pre-registration at the panel
• Time-limited access with automatic expiration
• Role-based authorization using existing UMC alias roles
• Seamless authentication via Bluetooth
• No cloud dependency, no central server required
Simple workflow
Engineers configure roles in TIA Portal, generate Access Keys, and securely share them with technicians.
Technicians import the key into Unified Air and authenticate silently to nearby panels.
