Javaless authentication and electronic signature on the government's online services

This page was last modified on 06-02-2017

Since 6 February 2017, the access and electronic signature of documents have been simplified on the government's onlince services, such as MyGuichet, the Trade and Companies Register or the Central Balance Sheet Unit (Centrale des Bilans).

All web browser can now be used to carry out the procedures with the different online services. Java is no longer required.

The login and signature pages have also evolved in order to be more user-friendly.

If you're using a LuxTrust token, you will not be required to take any action.

Users of LuxTrust Smartcards and Sticks, as well as persons who use their Luxembourgish electronic identity card (eID), can still download the update from the LuxTrust website and avoid a service disruption.


The new version is necessary to access the government's online services and remains compatible with the current services.

The new middleware requires you to authorise pop-ups for the connection to the service and also for the electronic signature when invited to do so by your browser.

If you encounter any difficulties with updating the middleware, allowing pop-ups or any other technical issue, our Helpdesk is at your service to answer all your questions from Monday to Friday from 8.00 to 18.00. You can contact us by phone on (+352) 247-82000, use our contact form or visit us in person at the guichet counter.
