The invention concerns a system for executing a software whereof the access by a user is controlled by an accrediting data comprising a terminal (T), first storage means (F) associated with said software for storing at least a first accrediting data particular to said user, access-control means for authorising access to said software in response to a conformity between said first accrediting data and a second accrediting data applied via said terminal, and a security device (PSD) personal to said user, associated with said terminal, and comprising second storage means (M) for secure storage of said second accrediting data. The terminal (T) comprises, at least partly, means for managing the accrediting data (CMP) including means for reading said second accrediting data and transmitting to said access-control means in response to the presentation of a request for access to said software, and means for updating accrediting data for selectively controlling the generation and modification in said first (F) and second (M) storage means respectively a new accrediting data replacing the previously stored accrediting data.
