Python Client Library for Supabase Auth
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has no known vulnerabilities, installs with minimal friction, and provides a complete, well-documented authentication solution for Supabase users. Choose it if you're building on Supabase and need Python authentication; it's the official client library for that platform.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- You must provide a valid Supabase Auth URL and API key to initialize the client.
- Low install friction with three lightweight runtime dependencies (httpx, pydantic, pyjwt).

What it is and what it does
supabase_auth is a Python port of the Supabase JavaScript authentication client, providing a unified interface to Supabase Auth services. It wraps httpx for HTTP requests, pydantic for data validation, and pyjwt for token handling, offering both synchronous and asynchronous APIs so you can integrate authentication into blocking or async Python applications.
The library covers the full authentication lifecycle: user sign-up and sign-in (via email/password, OAuth, magic links, phone OTP, or anonymous mode), session management with automatic token refresh, multi-factor authentication enrollment and verification, and user profile updates. Errors are raised as exceptions rather than returned as tuples, following Python conventions, and datetime strings are automatically parsed into Python datetime objects.
Use it for
- Building a FastAPI or async web application that needs user authentication with Supabase backend
- Implementing multi-factor authentication flows in a Python backend service
- Integrating OAuth sign-in (e.g., Google, GitHub) into a Django or Flask application
- Managing user sessions and token refresh in a long-running daemon or background worker
- Handling phone-based or email OTP authentication for mobile app backends
