For any reimbursement request, please contact our Customer Support Desk by email only at questions@luxtrust.lu.

To equip you with a LuxTrust certificate or product, we need to identify you in person (or equivalent). In case you do not have the possibility to come at our premises, you can order a product either through video identification or using notary certified documents with apostille (of the Hague).

Order a product via video identification

Two products are currently available through a video identification process:

• digital identity for personal use associated with the LuxTrust App - order here.
• digital identity for professional use associated with the LuxTrust SmartCard - order here.

Please make sure you meet the eligibility criteria for a video identification process before ordering.

Order a product using notary certified documents with apostille

Getting identified by a notary, in accordance with the Hague Convention of 5 October 1961, is an alternative to face-to-face or video identification.

In case you opt for this type of identification, you need to provide us a copy of your identity card or passport, duly certified by a notary. This copy must bear an apostille and must be legible according to the standards applicable to Luxembourg (alphabet, language, etc.).

Then, please send it by mail along with your printed order file to:

To get through a video identification process, you need:

• a smartphone (supporting at least iOS 12 or Android 6) with microphone and good camera functionalities
• the same valid ID document you used during the ordering process
• your VideoID code received during the ordering process
• a good Internet connection and phone signal
• to be alone, in a quiet and calm place

If the video identification process was successful and your identity has been validated, you will receive your LuxTrust codes by SMS within 24 hours after your video session.

You can check the exact expiration date of your LuxTrust certificate at any time by logging into your MyLuxTrust area in the Test my certificate section.

LuxTrust provides you with a multitude of options to benefit from a trusted digital identity. Most of our partners support all our devices, but some of them may have specific requirements.  

In order to find the product that best fits your needs, take a few moments and ask yourself the following questions: 

• Do I need a device for professional or personal use?
• For what type of operations will I use it? Is it for registering for VAT, filling my taxes, connecting to my bank or something else?
• Does my provider support the device or product I chose?
• Can I come to LuxTrust’s office in Luxembourg to get identified?

You can also check here the list of devices accepted by each of our partners.

If you were unable to complete your video identification session due to technical reasons, please contact our Customer Support Desk at +(352) 24 550 550 or by email at questions@luxtrust.lu. We can then either help you restart the process or refund you.

If the session was not validated because your ID document was not compliant or valid, no reimbursement is possible.

The certificate, to which your device is linked, is valid for three years. We will inform and invite you to renew your certificate when it is about to expire.

If your VideoID activation code is still valid, the system allows you to start again the process.

If your code has expired, please contact our Customer Support Desk at +(352) 24 550 550 or by email at questions@luxtrust.lu.

If you reach the point when you have to speak with an operator and you receive the following message “Please wait, an operator will answer as soon as possible”, it will usually take a few more minutes until you can speak with one. If you can no longer wait, please resume the session at a more convenient time.

If, after several attempts, you could not still get in touch with an operator, please contact our Customer Support Desk at +(352) 24 550 550 or by email at questions@luxtrust.lu.

To be eligible for video identification process, you must:

• Be over 18 years old
• Have valid and accepted ID document (preferably passport) - see the list of accepted documents by country
• Have a smartphone or tablet running on at least iOS 12 or Android 6

You are not eligible? Then, you will need to get identified in person.

Unfortunately, it is not yet possible to change or upgrade your private certificate into a professional one.

If you need a professional certificate, you can order one here.

For the time being, contact our Customer Service Desk at (+352) 24 550 550 to update your data.

If you already have a LuxTrust Token or the LuxTrust app, you can associate a LuxTrust Scan to your certificate.

• If you are equipped with the LuxTrust app, go to your MyLuxTrust area under Manage my products and click on Add a device to associate your LuxTrust Scan.
• If you only have a Token, call our Customer Service Desk at (+352) 24 550 550.

Once your Scan is linked to your LuxTrust certificate, you can handle it using the UserID and password of your Token or LuxTrust app.

For information, the Scan cannot be associated with a certificate linked to a SmartCard or a Signing Stick.

• If you have a Token, Scan or the LuxTrust app, go to your MyLuxTrust area in Change my password.

You can enhance your security by regularly changing your password or PIN code.

If you want to temporarily disable access to one of your LuxTrust products (for example, in the event of theft or loss), there are 2 available options:

You have just finished the installation and restarted your computer, but the LuxTrust Middleware does not start. The following error message appears:

“The LuxTrust Middleware cannot be started. Another session is already running on your computer under another user of your operating system. Please log into the other user account and close the session. Then restart the LuxTrust Middleware.”

When you see this message, it could be that:

• you have 2 active sessions. So, you have log in first under the other user to close the session and then restart the LuxTrust Middleware.
• the port is already used by another application. In this case, you have to stop the other application or change the port of the other application. LuxTrust Middleware acts as a local server and is connected to port 24727. If another application is using the same port, the error message above can appear.
• you have an OpenEcard app installed. So, you have to stop this application as it uses the same port as the LuxTrust Middleware.

If your Smartcard/Signing Stick is not recognised by the LuxTrust Middleware, you should:

• Make sure your device is duly connected to your computer
• Close the LuxTrust Middleware by clicking on Exit
• Restart the LuxTrust Middleware

If the issue persists, please contact our Customer Service Desk at +(352) 24 550 550.

For security reasons, your account is blocked after 5 failed logins. It will be automatically unlocked after 12 hours. Once unlocked, we advise you to set a new password.

If you have a LuxTrust SmartCard or Signing Stick, you have probably blocked your PIN code. To solve the issue, please follow the procedure according to your operating system:

• Unblock on Windows
• Unblock on Mac
• Unblock on Ubuntu

If you have lost your LuxTrust device or it got stolen, immediately contact our Customer Service Desk at +(352) 24 550 550 and ask your certificate to be suspended.

You can also temporarily suspend your certificate in your MyLuxTrust area. For this, you will need your initial codes received when you first ordered the device.

Depending on your situation, you can either order and associate a new device to your account or revoke your certificate and order a new one. If you have questions about which action to take, please contact our Customer Service Desk at +(352) 24 550 550.

If your LuxTrust product is faulty (out of service, the screen is unreadable, etc.), please:

2. Return us the faulty device by post, in person at our offices or by handing over your Token or Scan to your bank branch.

We will give you a new device free of charge. You will keep your UserID and Password.

If you have changed your phone or it has been stolen, there are 2 possible options:

1. If you have a Token or Scan linked to the same certificate as your LuxTrust app: you can re-download the app and proceed to its activation. As a precaution, you should suspend access to your old phone. To do this, go to your MyLuxTrust area in Manage my products section.
    
2. You don’t have any other additional device: please contact our Customer Service Desk at +(352) 24 550 550. A LuxTrust operator will help you associate the app with your account and suspend the access to your old phone.

If you do not see your secret image when you enter your OTP or PIN code or it is not the one you have chosen, then you are most likely on a pirate site imitating LuxTrust. Cancel the transaction and call our Customer Service Desk at +(352) 24 550 550 to report it.

As a reminder, you will not see your secret image if you are using the LuxTrust app or Scan.

In case you leave the company, you (as delegated user) or your employer should revoke the digital certificate associated with to your device.

For security reasons, we encourage you to revoke it yourself (action available in your MyLuxTrust area). If you also have a device such as a Smartcard or Signing Sick, please destroy it as you would normally do with a credit card.

You can change the notification email, postal address or phone number of your active professional certificate. The intracommunity VAT number can only be changed in the billing address. To do so, please contact our Customer Service Desk at +(352) 24 550 550.

However, you cannot modify the company name or the email address displayed when you apply an electronic signature using your certificate. If you want a certificate with this new data, you will need to order a new one.

Within the European Union, an electronic signature cannot be dismissed solely on the grounds of its format. In the case of the qualified electronic signature, its legal value is equivalent to that of a handwritten signature. However, in case of litigation, it is possible to dispute the validity of this type of e-signature. It will then be necessary to provide proof that it was created through fraudulent means.

The burden of proof in case of dispute of an electronic signature

If the e-signature is qualified, it is commonly acknowledge that it has the legal equivalent of a handwritten signature. It will therefore be up to the party who challenges the signature to prove that it cannot be assimilated to a handwritten signature in a specific case.

On the other hand, if the electronic signature is advanced, the electronic signature is not a priori assimilated to a handwritten signature. So, it will be up to the party who invokes the validity of the electronic signature to prove that the signature electronic has been made in such a way that it can have the legal value of a handwritten signature.

Thus, the user of a device allowing him to electronically sign documents at the qualified level will be in a better position in case a co-contractor in an EU country challenges his electronic signature.

How to obtain evidence in the event of a dispute

Support in the event of a dispute will depend on your chosen service provider and the level of signature you used.

If you are a LuxTrust customer or the dispute is related to the use of a LuxTrust signature certificate, you can contact our customer service who can provide the competent authorities with the audit trail related to the use of your certificate. It remains the user's responsibility not to share the elements of his LuxTrust digital identity (UserID, password, OTP or PIN code in the case of chip-based products) with a third party.

It is possible to send you the list of active certificates linked to your organisation for 100€ excluding VAT.

You have to 2 options to make this request:

1. If you have an employee with a "certificate administrator" certificate on behalf of your company, this person can send us a request signed electronically by email to questions@luxtrust.lu.
    
2. You can send a written request signed by a company representative. This request must be accompanied by a copy of the signer’s identity document as well as recent proof that s/he is authorised to sign on behalf of the company (e.g.: extract from the trade register).

The professional digital certificate allows you to authenticate and sign on behalf of the organisation that employs you. So, in order to issue such a certificate, we need to get the authorisation of your employer besides checking your personal data.

An electronic signature certificate is a document in digital form that contains data related to a natural person. The certificate is issued by a Certificate Authority and a trust service provider. The certificate (also known as a digital identity) binds the identity of the owner to his or her electronic signature.

The most notable difference between a qualified and an advanced electronic signature (as defined in eIDAS Regulation) becomes apparent in case of legal disputes or when a party contests the validity of an electronic signature.

The qualified level enjoys legal recognition and acceptance across all EU member states. It is the only one having the legal equivalent of a handwritten signature. This means that, in case of a dispute, the judge will view the qualified electronic signature in the same light as a handwritten signature. In addition, its validity is presumed and the reverse burden of proof principle is applied. So, the party contesting the signature will have to prove that the qualified e-signature is invalid.

If, on the other hand, the electronic signature is advanced, then the party who claims its validity will have to prove to the court that the advanced e-signature is indeed valid.

The security of your personal data is of utmost importance for us. We ensure that your data is protected in the best possible way and according to the European Regulation for Electronic Identification (eIDAS) and the General Data Protection Regulation (GDPR).

Companies working with LuxTrust request only the strictly necessary data and confirm that they will not use it without your permission.

LuxTrust shares your data only when you have explicitly given your permission each time. With LuxTrust, you are always in charge of your personal data.

Your one-time password (OTP) is valid for 180 seconds or 3 minutes. As its name suggests, it can only be used once.

If you have to perform a more sensitive transaction, your service provider will most likely ask you for a second OTP. You will need to generate it again with the help of your LuxTrust Token, Scan or the LuxTrust app.

When you receive a communication (by email or SMS), there are several elements that you should check as they might indicate you are dealing with a fraud attempt:

• Sender’s address or telephone number: they have unusual formats and do not match with the corporate emails or phone numbers you used to communicate previously with your service supplier.
• The type of demand / request: such communications almost always contain an urgent demand such as to update your data or provide some information to continue accessing a service.
• Links: most service providers will never send you a link by email or SMS asking to update your data.
• Spelling: a large number of errors in the wording can be a sign of a fraud attempt.

OTP stands for “one-time password”. It is a code generated by a security device (Token, Scan etc.) that is valid for a limited timeframe and only for a single session or transaction. You use it to complete traditional static passwords. Once you use it or its validity time passed, the device generates a new one according to an algorithm linking your digital identity to LuxTrust servers.

Phishing attempts are more and more numerous and hackers mimic very well the websites of your service providers. Be careful not to share your personal data (UserID, passwords, OTPs) via these websites. If in doubt, please contact our Customer Service Desk at +(352) 24 550 550.

If you have unfortunately shared your personal codes, passwords or data through what you suspect to be a fake website, report it to immediately LuxTrust. Call our Customer Service Desk at (+352) 24 550 550 to suspend your certificate. Please also contact your bank to block any transaction.

Please always bear in mind that LuxTrust will never ask you to update or share your personal information by email or SMS.
