For commissioning, programming and coding of ECUs (XENTRY Flash) an additional, second authentication is mandatory for each user. This process is similar to a TAN authentication as requiered for online banking.
For authentication, you need one of the following two factors:
Smartphone authenticator app (e.g. PingID, Microsoft Authenticator)
USB security key
You can use any key of your choice, as long as it supports the FIDO2 standard.
Available from specialist electronics retailers or directly from the manufacturer.
We recommend that you set up both options right away. If you lose one of the authentication factors, you will be able to work with the second one!
To assist you in setting up the factors, we will provide you with a compact HelpCard for download.

If you are no longer able to authenticate, you have several options:
1) If you have lost/forgotten your smartphone, but you have set up another second factor (USB security key), you can use that one.
2) If you don't have an alternative second factor set up, contact your org admin. The org admin can reset the second factor for you so that you can create a new one. If you don't know your Org admin, you can check it via Alice under your profile data. To do this, click on "Administrators".
Instructions for org admins on how to reset the second factor (PDF).
Whether for flashing, SCN/CVN coding or entering equipment codes: XENTRY Flash can be used with Mercedes-Benz Cars (including smart*, Maybach and SLR) as well as with Mercedes-Benz Vans. For trucks, we offer an online process for the parameterisation of control units, which speeds up data availability in the workshop after a control unit replacement.
Conveniently, all processes are fully integrated within the diagnostics software (XENTRY Diagnosis, XENTRY DAS) requiring fewer manual intervention from your mechanics.
* except smart model #1
After the programming of the control unit, the SCN coding (if permitted by the control unit) as well as the reverse documentation will run automatically in the VeDoc Vehicle Documentation System. Any changes made to the vehicle or the control unit software are updated on the VeDoc vehicle data card.
Once you are logged into one of our workshop applications (e.g. XENTRY Flash, WIS etc.), no further sign-on to the central online systems is required, resulting in smooth workflow in your workshop. The user is logged out of the online systems only after one hour of inactivity.

Technical support: If you have technical questions or feedback to the XENTRY Diagnosis products, please contact the XENTRY Diagnosis User Helpdesk (UHD) by creating a ticket in the Support Tool (wrench icon on the Desktop) on your XENTRY Diagnosis device or while in the XENTRY Diagnosis application clicking on the speech bubbles at the top right. Alternatively, open a ticket in B2B Connect in the “need help?” section or use the direct link to the XSF Ticketing System: https://xsf.i.mercedes-benz.com/support/arsys/SingleSignOn.
New diagnosis user rights as of 06/2020
With the introduction of the E-Class facelift and the new S-Class, a new security concept is being introduced, which will also have a significant impact on the use of XENTRY Diagnosis software.
As of the 06/2020 data release, a prompt to enter a personalised user name and password will appear when accessing the new E-Class and S-Class. It is not possible to diagnose these vehicles without entering this information. This means that these vehicles can no longer be repaired/diagnosed without diagnosis access authorisation. Every user must go through an identification process in order to acquire the corresponding user rights for the facelift of the E-Class and subsequent models. Please note that it is no longer possible to diagnose these model series with a XENTRY Diagnosis Kit 2. You will need a XENTRY Diagnosis Kit 3 as a minimum.
A distinction is made between two types of user rights:
XENTRY Standard Diagnosis (for diagnosis users without XENTRY Flash authorisation, e.g. for reading and erasing fault memories)
XENTRY Flash user (corresponds to the current XENTRY Flash user)
Please use one of the following options:
XENTRY Flash rights:
User already has Flash rights: Every Flash user must independently go through the one-off identification process at https://umas.mercedes-benz.com/umas.
User does not have Flash rights: User must request XENTRY Flash rights through the market-specific channel. They must then go through the identification process at https://umas.mercedes-benz.com/umas
XENTRY Standard Diagnosis rights:
Every diagnosis user must independently request the Standard Diagnosis rights via https://umas.mercedes-benz.com/umas and run through the one-off identification process. It may also be necessary for the market-specific ISP support to create the user in GEMS if they do not yet have a user ID.
The vehicles are developing ever gradually into a "mobile computer". This in turn makes the vehicles the target object for hacker attacks and misuse. The number of news items in the press has grown massively. UNECE regulations will, in future, require protection of the vehicles. Mercedes-Benz is also introducing corresponding security measures.
To help protect against any unauthorized diagnosis access, the new Mercedes-Benz vehicle software architecture is now available with user-related security certificates.
Certificate-based diagnosis was introduced in E-Class facelift vehicles (model series W213 facelift) with individual control units. The S-Class W223 saw the full introduction.
In future, all new model series and facelifts will be equipped with certificate-based diagnosis.
In future, to enable diagnosis to be performed, you will require a certificate provided by the manufacturer. At the start of a diagnosis session, this certificate is exchanged between the tester and the vehicle. This process is filed in the tester application and it runs in the background.
You are an independent workshop:
If you own a XENTRY Diagnosis Kit 3 or 4, or if you use XENTRY Pass Thru EU, the certificates are provided by Mercedes-Benz AG.
If you own a diagnosis tool from an independent manufacturer, the certificates are provided by the tool manufacturer, if it has concluded a data license agreement with Mercedes-Benz AG.
You are a diagnosis tool manufacturer:
Please follow the instructions on the site https://b2bconnect.mercedes-benz.com/GB/technical-data
You are a technical inspection agency or an official bureau:
Please get in touch with us using firstname.lastname@example.org.
The certificates are made available by Mercedes-Benz AG to all customers free of charge.
This is dependent on the level of access involved.
Read access authorizations are bound to an organization and they must be issued for an organization/service operation
Write access authorizations are personalized and require previous personal authentication - either at Mercedes-Benz AG or at the independent tool manufacturer.
OBD-II functions (SAE J1979) are still available without any restrictions.
For all further functions, diagnosis certificates are required that are either bound to an organization or to a person, depending on the level of access authorization involved.
