Reusable authentication core and FastAPI/SQLAlchemy adapters for Orcestr applications.

orcestr-auth

Python authentication core and FastAPI/SQLAlchemy adapters for the Orcestr ecosystem.

The application keeps its real user model and product lifecycle. The package owns password, token, session, cookie, recovery, OAuth and WebSocket authentication mechanics.

Install

pip install "orcestr-auth[all]"

Optional groups:

Extra	Includes
fastapi	dependencies, cookie/CSRF flow and router factory
sqlalchemy	auth models, direct user repository and Alembic operations
oauth	GitHub, Google and Yandex provider clients
all	every first-party adapter

Main APIs

Import	Purpose
orcestr_auth	config, password helpers, token codec and extension ports
orcestr_auth.sqlalchemy	create_auth_models, UserFieldMap, user repository
orcestr_auth.services	sessions, verification/reset codes and WebSocket tickets
orcestr_auth.oauth	optional provider clients and normalized profiles
orcestr_auth.fastapi	auth dependencies, redirect policy and router factory
orcestr_auth.migrations	versioned Alembic operations for auth-owned schema

SQLAlchemy Wiring

Attach auth tables to the application's registry and real user primary key:

from orcestr_auth.sqlalchemy import UserFieldMap, create_auth_models

auth_models = create_auth_models(
    registry=Base.registry,
    user_model=UserORM,
)

user_fields = UserFieldMap(
    id=UserORM.id,
    username=UserORM.username,
    email=UserORM.email,
    password_hash=UserORM.password_hash,
    is_active=UserORM.is_active,
    email_verified_at=UserORM.email_verified_at,
)

This creates direct indexed queries and real foreign keys. It does not create a second user table and does not use runtime reflection.

FastAPI Wiring

from orcestr_auth.fastapi import create_auth_dependencies, create_auth_router

auth_dependencies = create_auth_dependencies(
    config=auth_config,
    session_dependency=get_control_db_session,
    user_model=UserORM,
    user_fields=user_fields,
    models=auth_models,
)

router = create_auth_router(
    config=auth_config,
    application_dependency=get_auth_http_application,
    current_user_dependency=auth_dependencies.current_user,
    register_model=RegisterRequest,
    user_response_model=UserRead,
)

The consumer implements the small AuthHttpApplication boundary for product-specific work: user creation, legal acceptance, tenant bootstrap, email delivery, audit and rate limits. Standard endpoints, cookies and token responses remain library-owned.

Security Model

• browser tokens live in HttpOnly cookies and never appear in browser auth JSON;
• cookie mutations require the configured CSRF header;
• refresh tokens are opaque, hashed, rotated and replay-protected;
• access JWTs validate issuer, audience, expiry, type, JTI and server session state;
• recovery codes are hashed, expiring, attempt-limited and one-time;
• OAuth validates redirects and supports state/PKCE without implicit account linking;
• WebSocket access uses short-lived one-time tickets.
