In today’s automotive repair landscape, security is paramount. As a content creator for xentryportal.store and an automotive repair expert, I understand the critical importance of secure diagnostic processes. This article delves into the enhanced security measures implemented in XENTRY Diagnosis, focusing specifically on Xentry Flash Access Authorization. Building upon the original information, this guide offers a comprehensive and SEO-optimized explanation for English-speaking automotive professionals.
XENTRY Diagnosis has significantly bolstered its security framework, particularly for ECU commissioning, programming, and coding via XENTRY Flash. This enhancement mandates a secondary authentication step for each user, adding a robust layer of protection akin to online banking’s Transaction Authentication Number (TAN) system. This multi-factor authentication ensures that only authorized personnel can perform critical vehicle software operations.
To gain xentry flash access authorization, you will need to establish a second authentication factor. Mercedes-Benz provides two convenient and secure options:
-
Smartphone Authenticator App: Utilize an authenticator application such as PingID or Microsoft Authenticator on your smartphone. This method provides a dynamic and secure way to verify your identity.
-
USB Security Key: Employ a USB security key that adheres to the FIDO2 standard. These keys are readily available from electronics retailers and offer a physical hardware-based authentication method.

It is highly recommended to configure both authentication methods from the outset. This redundancy ensures continued access to XENTRY Flash even if one authentication factor becomes unavailable, preventing workflow disruptions in your workshop. To facilitate the setup process, Mercedes-Benz offers a concise HelpCard, available for download, guiding you through each step.
Recovering Access: Resetting Your Second Factor
Situations may arise where you lose access to your second authentication factor. XENTRY Diagnosis provides several recovery options to regain xentry flash access authorization:
-
Utilize an Alternate Second Factor: If you have configured both a smartphone authenticator app and a USB security key, and you lose access to one, simply use the functioning alternative to authenticate.
-
Contact Your Organization Administrator: If you lack an alternative second factor, your organization administrator can reset your authentication settings. This allows you to establish a new second factor and regain access. You can identify your Organization Administrator through the Alice platform under your profile data by clicking on “Administrators.”

Organization administrators can find detailed instructions on resetting the second factor in a dedicated PDF document provided by Mercedes-Benz, ensuring a smooth and secure recovery process for xentry flash access authorization.
Versatile Applications of XENTRY Flash
Xentry flash access authorization unlocks a wide spectrum of essential workshop operations across the Mercedes-Benz vehicle range, encompassing Mercedes-Benz Cars (including smart*, Maybach, and SLR) and Mercedes-Benz Vans. Conveniently integrated within XENTRY Diagnosis and XENTRY DAS software, XENTRY Flash streamlines processes like:
- ECU Flashing: Updating and reprogramming engine control units and other electronic modules.
- SCN/CVN Coding: Performing Software Calibration Number (SCN) coding and Calibration Verification Number (CVN) coding for proper component configuration and system adaptation.
- Equipment Code Entry: Inputting equipment codes to accurately reflect vehicle options and configurations.
This seamless integration minimizes manual interventions by technicians, enhancing efficiency and reducing the potential for errors during complex procedures requiring xentry flash access authorization.

Automated SCN Coding and VeDoc Documentation
After successfully programming a control unit using xentry flash access authorization, the system automates crucial post-programming steps. SCN coding, when permitted by the control unit, and VeDoc (Vehicle Documentation) reverse documentation are executed automatically. This ensures that any modifications to the vehicle or its control unit software are accurately and immediately updated within the VeDoc vehicle data card, maintaining a comprehensive and up-to-date vehicle history.
Streamlined Workflow with Single Sign-On
The Single Sign-On (SSO) feature further enhances workshop efficiency when utilizing xentry flash access authorization. Once logged into one Mercedes-Benz workshop application (such as XENTRY Flash, WIS, or others), subsequent access to central online systems is granted without requiring repeated sign-ins. This eliminates redundant login procedures, contributing to smoother workflows and saving valuable technician time.
Understanding Diagnosis User Rights
New diagnosis user rights were introduced in June 2020, coinciding with the launch of the E-Class facelift and the new S-Class. This update introduced a refined security concept that significantly impacts XENTRY Diagnosis software and xentry flash access authorization.
Starting with the June 2020 data release, accessing the new E-Class and S-Class models necessitates entering a personalized username and password. Diagnosing these vehicles is impossible without this authentication, meaning diagnosis access authorization is now mandatory for these models. Furthermore, diagnosing these newer series is no longer feasible with a XENTRY Diagnosis Kit 2; a XENTRY Diagnosis Kit 3 or later is required.
Two distinct user right categories are defined:
- XENTRY Standard Diagnosis: Intended for users who do not require xentry flash authorization. This level permits basic diagnostic functions like reading and clearing fault codes.
- XENTRY Flash User: Corresponds to the previous level of XENTRY Flash access, granting full programming and coding capabilities.
To acquire the appropriate user rights, utilize the UMAS (User Management and Authorization System) platform:
-
XENTRY Flash Authorization: Both Standard-Flash and Extended Flash roles (for all CeBAS vehicles) are obtainable via UMAS. Each user must complete a one-time identification process through UMAS to obtain xentry flash authorization.
-
XENTRY Standard Diagnosis Rights: Every diagnosis user must independently request Standard Diagnosis rights via https://umas.mercedes-benz.com/umas and undergo the one-off identification process. In some market-specific instances, the ISP support may need to create the user in GEMS if a user ID is not yet established.
The Necessity of Certificate-Based Diagnosis
The increasing sophistication of vehicles, transforming them into “mobile computers,” unfortunately also makes them prime targets for cyberattacks and unauthorized access. Growing media coverage of such threats and upcoming UNECE regulations mandating vehicle protection have driven Mercedes-Benz to implement advanced security measures.
To safeguard against unauthorized diagnosis attempts, Mercedes-Benz has introduced a new vehicle software architecture featuring user-related security certificates. This certificate-based diagnosis system is a cornerstone of enhanced xentry flash access authorization and overall vehicle security.
Vehicle Models Implementing Certificate-Based Diagnosis
Certificate-based diagnosis was initially implemented in E-Class facelift vehicles (model series W213 facelift) for individual control units, with full integration in the S-Class W223. Moving forward, all new Mercedes-Benz model series and facelifts will incorporate certificate-based diagnosis as a standard security feature.
Changes to the Diagnostic Process
With the introduction of certificate-based diagnosis, performing diagnostics now requires a digital certificate issued by the manufacturer. At the commencement of a diagnosis session, this certificate is securely exchanged between the diagnostic tester and the vehicle. This certificate exchange process is automated within the tester application and operates seamlessly in the background, ensuring a secure and transparent process for users with valid xentry flash access authorization.
Obtaining Certificates: Registration Process
The certificate acquisition process varies based on your workshop type:
Independent Workshops:
- XENTRY Diagnosis Kit 3 or 4, or XENTRY Pass Thru EU Users: Certificates are directly provided by Mercedes-Benz AG.
- Independent Manufacturer Diagnosis Tool Users: Certificates are provided by your tool manufacturer, provided they have a data agreement with Mercedes-Benz AG.
