Le « flux » `password` est l'une des manières (« flows ») définies dans OAuth2 pour gérer la sécurité et l'authentification.

OAuth2 a été conçu pour que le backend ou l'API puisse être indépendant du serveur qui authentifie l'utilisateur.

Mais dans ce cas, la même application **FastAPI** gérera l'API et l'authentification.

Voyons cela selon ce point de vue simplifié :

```toml
[tool.fastapi]
entrypoint = "my_app.main:app"
```

### Use `fastapi` with a path

When adding the entrypoint to `pyproject.toml` is not possible, or the user explicitly asks not to, or it's running an independent small app, you can pass the app file path to the `fastapi` command:

```bash
fastapi dev my_app/main.py
```

Prefer to set the entrypoint in `pyproject.toml` when possible.

## Use `Annotated`

        assertEquals(1, chain.deleteCalls.size());
        assertEquals(1, chain.changePasswordCalls.size());
        assertEquals(1, chain.loadCalls.size());

        // Verify independence of operations
        assertEquals(user1, chain.updateCalls.get(0));
        assertEquals(user2, chain.deleteCalls.get(0));
        assertEquals("user3", chain.changePasswordCalls.get(0).getKey());

        assertTrue(result.length() > "TransPeekNamedPipeResponse[]".length());
    }

    @Test
    @DisplayName("Multiple instances should be independent")
    void testMultipleInstances() {
        // Arrange
        TransPeekNamedPipeResponse response1 = new TransPeekNamedPipeResponse(mockConfig);

This was changed in FastAPI 0.106.0 with the intention to not hold resources while waiting for the response to travel through the network.

/// tip

Additionally, a background task is normally an independent set of logic that should be handled separately, with its own resources (e.g. its own database connection).

So, this way you will probably have cleaner code.

///

// For objects with legal hold header set, the s3:PutObjectLegalHold permission is expected to be set
// Both legal hold and retention can be applied independently on an object

But that means that if you just convert it to a string and return that information directly, you could be leaking a bit of information about your system, that's why here the code extracts and shows each error independently.

///

### Use the `RequestValidationError` body { #use-the-requestvalidationerror-body }

The `RequestValidationError` contains the `body` it received with invalid data.
