About Service Accounts
Service Accounts provide many benefits of security and scale. Conceptually, a service account is a child resource of your Enterprise Account, and its permissions can never exceed the boundaries of that Enterprise Account.
Service Accounts are not users
Service Accounts are intended to be used purely as programmatic actors. They are not assigned login credentials, and can only be used with the Enterprise API.
For certain scenarios, Service Accounts may be utilized in a system of your design to provide end-user client experiences to users without requiring them to create a Samsung account.
Service accounts are designed to scale to your needs
Service Accounts themselves are beholden to platform rate limits, but if one does not suit your needs, you may choose to design a system to provision them dynamically, or simply generate a pool of pre-made service accounts to mitigate rate limiting.
