You cannot log in to your account with the same credentials on multiple computers or other devices simultaneously. Any sharing of credentials carries a major risk: the disconnection of the registered user and, consequently, the potential loss of content currently being edited :

For security reasons, each user must have their own credentials in order to log in simultaneously to the same account. Furthermore, each user must be assigned their own licenses in order to use the applications in the Sarbacane Suite.
This means that if several users wish to access the Sarbacane applications from several computers, each of them must log in separately on each device using their own credentials and must have their own operating licenses for the desired applications.
To avoid any inconvenience, you can independently purchase individual licenses on the Sarbacane Store.
