User accounts can also be used for which of the following functions?

User accounts serve a wide range of functions beyond simply granting access to emails or being limited to administrator roles. One significant use of user accounts is for machine entities, such as service accounts. Service accounts are special types of user accounts designed to facilitate automated tasks and processes that require services or applications to run without human intervention. These accounts often have specific permissions tailored to the needs of the applications they support, allowing them to perform functions like accessing databases or managing system operations.

This versatility is crucial in environments where automated processes need to operate seamlessly, ensuring that applications can function as intended without manual oversight. Thus, service accounts play a key role in maintaining operational efficiency and security within systems by isolating privileges and access based on the needs of applications rather than human users.
