FastAPI create auth for all endpoints

Question

I followed this documentation to setup up a single user: https://fastapi.tiangolo.com/advanced/security/http-basic-auth/

But I only get prompted for user/pass for that one end point, "/users/me".

How do I ensure that all endpoints are behind auth?

Answer 1

You can configure FastAPI with a set of dependencies that needs to be resolved for any endpoint by giving the paramter directly when creating the FastAPI application (i.e. global dependencies):

security = HTTPBasic()

app = FastAPI(dependencies=[Depends(security)])

If you want some endpoints to be authenticated and some to be unauthenticated, you can create separate instances of APIRouter, then assign required dependencies to the one that require authentication:

unauthenticated_router = APIRouter()
authenticated_router = APIRouter(dependencies=[Depends(security)])

.. and then either include other routers under each (using .include_router) or register endpoints as you'd do with the app object - but instead use your two routers.
