# pyobjc-framework-AuthenticationServices — Wrappers for the framework AuthenticationServices on macOS

License: permissive · Maintenance: active · Downloads: 656.3K/mo

## What it is and what it does

This package is a PyObjC wrapper layer that exposes Apple's AuthenticationServices framework to Python developers on macOS. AuthenticationServices provides native APIs for handling user authentication, including support for passkeys, Sign in with Apple, and other credential-based authentication flows. The wrapper translates Objective-C method calls and types into Python equivalents, allowing you to call AuthenticationServices directly from Python code.

To use it, you install the package alongside its runtime dependencies (pyobjc-core and pyobjc-framework-Cocoa), then import the framework classes and instantiate them as you would in native Objective-C code. The package itself does not include documentation—you rely on Apple's AuthenticationServices documentation and PyObjC's general translation guidelines to understand how to call each API. It is actively maintained, supports modern Python versions including free-threading builds, and carries no known security vulnerabilities.

Use it for:

- Build a macOS desktop app that integrates Sign in with Apple for user authentication.
- Implement passkey-based authentication in a native macOS application written in Python.
- Access native credential storage and management APIs from a Python-based macOS utility.
- Create a macOS security tool that leverages AuthenticationServices for multi-factor authentication flows.
- Develop a macOS app launcher or system utility that delegates authentication to the OS.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to macOS's AuthenticationServices framework, enabling integration with native authentication and credential management APIs.

Yes, if you are building a macOS application in Python and need native authentication APIs. The package is actively maintained, has no known vulnerabilities, and supports current Python versions. Install only on macOS; it is not useful on other platforms. Expect to consult Apple's AuthenticationServices documentation alongside PyObjC's translation guides, as the wrapper itself includes no usage docs.

## Install

pip install pyobjc-framework-authenticationservices
uv add pyobjc-framework-authenticationservices
poetry add pyobjc-framework-authenticationservices

## Installing pyobjc-framework-AuthenticationServices

Before you install: Medium friction: platform-specific wheels for macOS only (Python 3.10–3.15, including free-threading variants), requiring pyobjc-core and pyobjc-framework-Cocoa as runtime dependencies. Last release 3 days ago; repository active with recent commits.

License in practice: MIT license is permissive; no restrictions on commercial or proprietary use, modification, or redistribution.

Quickstart:

pip install pyobjc-framework-authenticationservices

from AuthenticationServices import ASAuthorizationController
# Use ASAuthorizationController to manage authentication requests

macOS only; requires Python 3.10 or later; pyobjc-core and pyobjc-framework-Cocoa must be installed first.

Verify before relying:

- Whether the wrapper covers the full AuthenticationServices API surface or a subset.
- Specific macOS version requirements beyond the wheel metadata (e.g., minimum macOS version for each Python release).
- Whether passkey/Sign in with Apple functionality is fully exposed through the wrapper.
