FastAPI OAuth2 is a middleware-based social authentication mechanism supporting several OAuth2 providers. It leverages the social-core authentication backends and integrates seamlessly with FastAPI applications.

For integrating the package into an existing FastAPI application, the router with OAuth2 routes and the OAuth2Middleware with particular configs should be added to the application.

from fastapi import FastAPI
from fastapi_oauth2.middleware import OAuth2Middleware
from fastapi_oauth2.router import router as oauth2_router

app = FastAPI()
app.include_router(oauth2_router)
app.add_middleware(OAuth2Middleware, config=OAuth2Config(...))
