How do you set up MyGuichet.lu in Luxembourg in 2026?

First obtain a LuxTrust product (often LuxTrust Mobile through your bank) or activate the certificates on a Luxembourg eID card. Guichet help pages also allow certain eIDAS means of identification from other EU countries. Activate LuxTrust on the official LuxTrust site before you try MyGuichet registration.

On MyGuichet registration you enter an email address and your thirteen-digit Luxembourg national identification number (matricule). Confirm the email from usermanagement@security.public.lu, authenticate through the state eAccess portal with LuxTrust, eID or eIDAS, accept the conditions, and finish registration. Guichet then asks you to create a private eSpace; without that eSpace you cannot start most formalities even if login works. Letters about registration may go to the address held in the National Registry of Natural Persons (RNPP), so keep commune registration accurate.

Use MyGuichet for catalogue procedures linked from Guichet information sheets, including some declarations of change of usual residence when your commune supports the online path. CNS offers an insured eSpace for reimbursement statements, bank-detail updates, co-insurance certificates and European Health Insurance Card replacement requests once you are affiliated; see public healthcare. A Luxembourg bank account is often how newcomers first receive LuxTrust, which is why banking and digital ID travel together for many movers.

MyGuichet does not invent a residence title. Non-EU workers still follow Immigration rules for temporary authorisation and the plastic titre de séjour described in Apply for a residence permit. Treat Guichet.lu English pages as the live checklist; commune opening hours in Ville de Luxembourg or Esch still matter when a form needs an in-person stamp.
