Understand the scope

What is this process for?

The level and use of the signature depend on the product and the procedure. Do not share your personal means; arrange mandates and authorisations suited to the parties involved.

How to prepare the process

A LuxTrust product can be used for authentication and, depending on the product and service, for electronic signature. The identity of the authenticated person and their rights in the professional space are two separate matters. Sharing personal authentication means should be avoided: an employee or authorised representative must have the appropriate access. Plan for the renewal and removal of access when a person leaves.

A scenario to help you understand

Educational example

A manager delegates a procedure to their accountant by arranging the necessary rights, rather than giving them their personal authentication means.

The practical question

Que faire lorsqu’un collaborateur qui gérait les accès quitte l’entreprise ?

Préparez le retrait de ses droits et la continuité des démarches avant son départ. Les moyens d’authentification personnels ne doivent pas être transmis au remplaçant. Vérifiez les rôles dans chaque espace professionnel, les mandats et les dossiers en cours. Une liste d’accès tenue à jour évite de découvrir trop tard qu’une échéance dépend d’une seule personne.
