# Security Foundation

Restrict a user’s access to particular features in your Mac app or daemon.

## Overview

This document was previously titled *Authorization Services Objective-C Reference,* and it replaced the `SFAuthorization` chapter of the *Security Objective-C API* document. The other chapters of that document have been replaced by <doc://com.apple.documentation/documentation/SecurityInterface>.

The Security Foundation framework contains a single class, [`SFAuthorization`](/documentation/SecurityFoundation/SFAuthorization), which allows you to restrict a user’s access to particular features in your Mac app or daemon.
