Stytch python client
Decision gist · record as of 2026-08-14
Yes. The library is actively maintained, has no known vulnerabilities, installs cleanly with low friction, and uses a permissive MIT license. Install it if you are building on Stytch's platform and need a typed, well-documented Python client for B2C or B2B authentication flows.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; you must obtain a Stytch project ID and secret from the Stytch Dashboard.
- Low install friction with a pure-Python wheel distribution.
- Actively maintained with a recent release (51 days old) and ongoing repository activity.

What it is and what it does
Stytch is a Python client for Stytch's authentication-as-a-service platform. It wraps Stytch's REST API, letting you add passwordless authentication (email magic links, SMS/WhatsApp passcodes, WebAuthn, TOTPs), OAuth integrations, and session management to Python applications. The library supports both B2C (consumer) and B2B (organization-based) authentication flows.
Responses are fully typed using pydantic, so you get IDE autocomplete and runtime validation. Both sync and async methods are available for every endpoint—append `_async` to any method name to use it with asyncio. The library handles structured error responses through StytchError exceptions, letting you catch and respond to specific error types. It requires Python 3.10 or later and depends on aiohttp, requests, pydantic, and pyjwt for HTTP and JWT handling.
Use it for
- Add email magic link authentication to a web app without building your own email verification system.
- Implement B2B multi-tenant organization management with member invitations and SSO.
- Integrate OAuth logins (Google, GitHub, etc.) alongside passwordless methods in a single client.
- Build async authentication flows in FastAPI or other async frameworks using the `_async` methods.
- Handle session validation and token refresh for both consumer and enterprise applications.
