# Extra Data Types { #extra-data-types }

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

                    if (logger.isDebugEnabled()) {
                        logger.debug("Using default extractor {} for MIME type {}", extractorName, mimeType);
                    }
                    extractor = crawlerContainer.getComponent(extractorName);
                } else if (logger.isDebugEnabled()) {
                    logger.debug("Using {} for detected MIME type {}, not {}", extractor.getClass().getName(), detectedMimeType, mimeType);

**FastAPI** provides several tools, at different levels of abstraction, to implement these security features.

In this example we are going to use **OAuth2**, with the **Password** flow, using a **Bearer** token. We do that using the `OAuth2PasswordBearer` class.

/// info

A "bearer" token is not the only option.

But it's the best one for our use case.
