Hiya! Do you have code you could share for how you're mounting the middleware?

```from starlette.middleware.authentication import AuthenticationMiddleware
from starlette.responses import PlainTextResponse```

```from starlette.middleware.authentication import AuthenticationMiddleware
from starlette.responses import PlainTextResponse

class TokenAuth (BaseTokenAuth):
    async def verify(self, token: str):
        print('here 1 11111111111111111111111111')
        if token != 'test123':
            return None
        return True

svc.add_asgi_middleware(AuthenticationMiddleware, backend=TokenAuth(), on_error=lambda _, exc: PlainTextResponse(str(exc), status_code=401))```

I've tried with the basetokenauth backend

I assume this is done before the

```@svc.api(...)```

Just tried to implement on_error but nothing is thrown

Also tried to add '@requires('authenticated')' after @svc.api but i get the following error: `No "request" or "websocket" argument on function "&lt;function txt2img at 0x7ff87c9ce5e0&gt;"`

Ah, does the middleware require annotating the endpoints?

I think so, here's an example from their github <https://i.gyazo.com/eb6148714a1944e6485b0bf2587a46fa.png>

But I can't find how to do that with bento (and I am also new to Python btw)

I'm not sure that's actually possible, let me look into this a bit.

I chose to use starlette-auth-toolkit by following bentoml's article on Securing Endpoints Access here: <https://docs.bentoml.org/en/latest/guides/security.html>

Also, if you know any other way to secure my endpoints pls let me know
