Several accounts assigned to one NAS can be made on Synology. That means different users with their account can access a device according to their permissions. That fits great in the environment where various people or teams work together but have different access controls. It is possible to provide each and every user with his login credentials along with his access rights, which include reading or writing permissions to some folders or services. User account management via DSM or DiskStation Manager from Synology makes it rather a piece of cake to start tweaking further in security settings so that sensitive data stays in, while continuously sharing access among many users on the same NAS
