But what's a "timing attack"?

Let's imagine some attackers are trying to guess the username and password.

## Async vs Sync *path operations*

Use `async` *path operations* only when fully certain that the logic called inside is compatible with async and await (it's called with `await`) or that doesn't block.

```python
from fastapi import FastAPI

app = FastAPI()


# Use async def when calling async code
@app.get("/async-items/")
