Accessing critical diagnostic and programming functions for Mercedes-Benz vehicles requires a secure Xentry Scn Account. To enhance security and protect against unauthorized access, Mercedes-Benz has implemented multi-factor authentication (MFA) for all XENTRY applications. This added layer of security ensures that only authorized users can access sensitive vehicle data and perform critical functions like programming and coding.
Understanding XENTRY SCN Account Security
XENTRY SCN (Software Calibration Number) accounts are essential for workshops and technicians working on Mercedes-Benz vehicles. These accounts provide access to crucial functionalities, including:
- ECU Programming and Coding: Flashing and configuring Electronic Control Units (ECUs) with the latest software updates and calibrations.
- Diagnosis: Performing in-depth vehicle diagnostics to identify and troubleshoot issues.
- SCN Coding/CVN Coding: Generating and applying Software Calibration Numbers or Component Verification Numbers for various vehicle systems.
- Vehicle Documentation: Automatically documenting changes made to the vehicle or control unit software in the VeDoc system.
Multi-Factor Authentication: Enhancing XENTRY Security
MFA adds an extra layer of security beyond your username and password. It requires a second form of verification to confirm your identity before granting access to your XENTRY SCN account. This process is similar to the security measures used for online banking. Currently, XENTRY supports two MFA options:
- Smartphone Authenticator App: Utilize a compatible authenticator app on your smartphone, such as PingID or Microsoft Authenticator, to generate time-based one-time passwords (TOTP).
- USB Security Key: Employ a FIDO2-compliant USB security key for a hardware-based authentication method. These keys are widely available from electronics retailers.
We strongly recommend setting up both authentication methods for your XENTRY SCN account. This provides redundancy in case you lose access to one factor.
Resetting Your Second Factor
Losing access to your second authentication factor can be disruptive. Here’s how to regain access to your XENTRY SCN account:
- Alternative Factor: If you have both a smartphone authenticator app and a USB security key configured, you can use the available factor to log in and reset the lost one.
- Contact Your Organization Administrator: If you only have one factor configured and lose access to it, contact your organization’s XENTRY administrator. They can reset your MFA settings, allowing you to set up a new second factor. You can find your administrator’s information in the Alice platform under your profile data.
Certificate-Based Diagnosis for Enhanced Security
Modern Mercedes-Benz vehicles are essentially “computers on wheels,” making them vulnerable to cyberattacks. To combat unauthorized access, Mercedes-Benz has introduced certificate-based diagnosis. This system requires a valid certificate exchange between the diagnostic tool and the vehicle before allowing access. This added layer of protection ensures that only authorized personnel with the correct certificates can diagnose and service these vehicles. Certificate-based diagnosis was first introduced in the facelifted E-Class (W213) and fully implemented in the S-Class (W223). It will be standard in all future models and facelifts.
Obtaining XENTRY Diagnosis Certificates
- Independent Workshops: If you use a XENTRY Diagnosis Kit 3 or 4, or XENTRY Pass Thru EU, Mercedes-Benz AG provides the necessary certificates. If you use a third-party diagnostic tool, the tool manufacturer provides certificates if they have a data usage agreement with Mercedes-Benz AG.
- Diagnosis Tool Manufacturers: Tool manufacturers must establish a data agreement with Mercedes-Benz AG to provide certificates for their devices.
Single Sign-On for Seamless Workflow
XENTRY utilizes single sign-on (SSO) for convenient access to various workshop applications. Once logged in to one application (e.g., XENTRY Flash, WIS), you won’t need to re-authenticate for other applications. The system automatically logs you out after one hour of inactivity. This streamlined workflow enhances efficiency in the workshop.
XENTRY User Rights and Access Levels
Different levels of user rights control access to specific diagnostic and programming functions within XENTRY. These rights are managed through the User Management and Administration System (UMAS). There are two main types of user rights:
- XENTRY Standard Diagnosis: Allows users to perform basic diagnostic functions like reading and clearing fault codes but does not grant access to programming or coding functionalities.
- XENTRY Flash User: Grants access to programming and coding functionalities, including SCN/CVN coding and ECU flashing. This user role is further subdivided into Standard Flash and Extended Flash for specific vehicle models.
Conclusion: Ensuring XENTRY SCN Account Security
Protecting your XENTRY SCN account is crucial for maintaining the integrity of your diagnostic and programming capabilities. By embracing MFA and understanding certificate-based diagnosis, you can ensure secure access to vital vehicle data and functions. For more detailed information and assistance with setting up MFA, refer to the official Mercedes-Benz MFA guide.
