A Secure Token in macOS serves as a crucial component in managing user accounts and ensuring security when encrypting data with FileVault. Specifically, a Secure Token is a wrapped version of a key encryption key. It enables users to access encrypted data, as it pairs with a user's password to securely manage their encrypted files.

When FileVault, Apple’s disk encryption program, is enabled, the Secure Token is generated for users who have administrative rights on the system. This token allows users to unlock the encrypted disk and is essential for tasks such as enabling or disabling FileVault, as well as giving other users access to the encrypted volume.

Understanding this concept is vital for effectively managing macOS environments, especially when dealing with user permissions and data protection protocols. The other options do not accurately represent the function and purpose of Secure Tokens in macOS, as they pertain to different aspects of security and functionality within the operating system.
