Due to maintenance work, the MyGuichet.lu services (both the app and the web version) will be unavailable on 29 April 2026 from 6.30 to 9.00. Thank you for your understanding.

Strong authentication

A strong authentication means that you must use 2 separate elements to log in to a device or application. For example, in order to log in to MyGuichet.lu using LuxTrust Mobile, you need to use:

  1. your LuxTrust log-in credentials; and
  2. the device on which you have installed the mobile application.
