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

How can I get a LuxTrust certificate or product if I am not your client and I live outside Luxembourg?

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:

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

If you can no longer wait, please resume the session at a more convenient time.

Solutions for professionals

If I have a professional certificate, do I have to return the LuxTrust product if I leave the company?

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.

Can I change the data of my certificate after it was issued (VAT number, address, company name)?

You can change the VAT number, notification email, postal address or phone number of your active professional certificate. 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.

Can the electronic signature's validity be challenged in court?

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.

How do I get an overview of the active professional certificates registered in my organisation's name?

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).

Why do I need the authorisation of my employer for ordering a professional digital certificate?

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.

What is an electronic signature certificate?

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.

What is the difference between a qualified and an advanced 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.

Data protection and security

Are my personal data safe at LuxTrust?

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.

How long is my OTP valid for?

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.

How can I tell if I am dealing with a fraudulent communication?

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.

What is an OTP?

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.

What should I do if I think I am a phishing attempt victim (via email, SMS, fake website)?

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.
