Understand the scope

What is this process for?

User access, role, authority to represent the entity and service-specific certifications must be distinguished. Invitations must be controlled: a role without signing authority does not mean that documents in the space are invisible.

How to prepare the process

The professional space brings together the company's procedures and communications on MyGuichet.lu. Users' rights must correspond to their duties. Access to a space does not mean that every user can sign or complete every procedure. A clear organisation provides for those in charge, alternates and access removals, as well as message monitoring so that a request for additional information is not left unanswered.

A scenario to help you understand

Educational example

An SME appoints a space administrator and an alternate, then grants its service provider the rights required for its procedures.

The practical question

Comment organiser les accès lorsqu’un cabinet effectue les démarches ?

Définissez les droits et mandats utiles, les personnes autorisées à valider et la surveillance des messages. L’entreprise doit garder la visibilité sur les dossiers et les preuves. Prévoyez aussi le retrait des accès à la fin de la mission. Le partage de moyens personnels d’authentification n’est pas une solution de gestion des délégations.
