Managing Authentication Challenges: Resetting Your Second Factor
Understanding how to manage potential authentication issues is crucial for maintaining uninterrupted workflow. If you encounter difficulties authenticating, several recovery options are available:
- Alternative Second Factor: If you lose access to your primary authentication method (e.g., smartphone), but have configured a USB security key as a backup, simply use the alternative method to regain access.
- Organization Administrator Reset: In situations where you lack an alternative second factor, contact your organization’s administrator. They possess the authority to reset your second factor, enabling you to set up a new one. You can identify your Organization Administrator through the Alice platform under your profile data, by clicking on “Administrators”.
Comprehensive instructions for organization administrators on resetting second factors are available in a dedicated PDF document, ensuring they are equipped to support users effectively.

Automatic SCN Coding and VeDoc Integration: Efficiency and Accuracy
Following ECU programming, XENTRY reprogramming software automates critical post-programming steps to ensure accuracy and compliance. SCN coding, when permitted by the control unit, and VeDoc reverse documentation are executed automatically. This integration ensures that the VeDoc Vehicle Documentation System is consistently updated with any changes made to the vehicle or its control unit software, maintaining a comprehensive and accurate vehicle history.
Single Sign-On: Streamlined Workflow for Enhanced Productivity
To further optimize your workshop’s workflow, XENTRY Diagnosis incorporates a Single Sign-On (SSO) feature. Once logged into one XENTRY workshop application (such as XENTRY Flash, WIS, etc.), you gain automatic access to other connected online systems without repeated logins. This eliminates unnecessary interruptions and allows for a smoother, more efficient workday. The system maintains your logged-in status for up to one hour of inactivity, balancing convenience with security.
Evolving Diagnosis User Rights: Adapting to New Security Standards
The automotive industry’s increasing focus on security is reflected in the evolving user rights associated with diagnostic software. Introduced with the E-Class facelift and the new S-Class models, a new security concept significantly impacts how XENTRY Diagnosis is utilized.
Since June 2020, accessing newer E-Class and S-Class vehicles with XENTRY Diagnosis requires personalized user authentication. Without entering a valid username and password, diagnosing these models is impossible. This measure mandates diagnosis access authorization for servicing these vehicles and necessitates an identification process for every user to obtain the appropriate rights for these and subsequent models. Notably, XENTRY Diagnosis Kit 2 is no longer sufficient for these newer model series; a XENTRY Diagnosis Kit 3 or later is required.

Two distinct user right types are now in place:
- XENTRY Standard Diagnosis: For users without XENTRY Flash authorization, primarily for tasks like reading and clearing fault memories.
- XENTRY Flash User: Corresponds to the previous XENTRY Flash user role, granting access to ECU programming and related functions.
To acquire the necessary user rights, follow these steps via the UMAS platform:
- XENTRY Flash Authorization: Both Standard-Flash and Extended Flash roles (for all CeBAS vehicles) are obtainable through UMAS. Each user must complete a one-time identification process via UMAS to secure these roles.
- XENTRY Standard Diagnosis Rights: Every diagnosis user needs to independently request Standard Diagnosis rights via https://umas.mercedes-benz.com/umas and complete the one-off identification. Market-specific ISP support may need to create users in GEMS if a user ID is not already established.
Certificate-Based Diagnosis: A Foundation for Vehicle Security
The shift towards certificate-based diagnosis is a direct response to the increasing sophistication of vehicle technology and the growing threat of cyberattacks. Modern vehicles, functioning as “mobile computers,” are increasingly vulnerable to hacking and misuse. Recognizing this evolving landscape and anticipating future UNECE regulations mandating vehicle protection, Mercedes-Benz is proactively implementing robust security measures.
Certificate-based diagnosis, therefore, is a crucial security measure designed to protect against unauthorized access to vehicle systems. This architecture, now standard in new Mercedes-Benz vehicles, relies on user-related security certificates to authenticate diagnostic sessions.
