But in your application, for security, you should make sure you only add the scopes that the user is actually able to have, or the ones you have predefined.

## Declare scopes in *path operations* and dependencies

Now we declare that the *path operation* for `/users/me/items/` requires the scope `items`.

For this, we import and use `Security` from `fastapi`.
