These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

* An optional `client_secret` (we don't need it for our example).

/// info

The `OAuth2PasswordRequestForm` is not a special class for **FastAPI** as is `OAuth2PasswordBearer`.

`OAuth2PasswordBearer` makes **FastAPI** know that it is a security scheme. So it is added that way to OpenAPI.

But `OAuth2PasswordRequestForm` is just a class dependency that you could have written yourself, or you could have declared `Form` parameters directly.

### Other (Cleanup or Flake)

- Reverts the EventedPLEG feature (beta, but disabled by default) back to alpha for a known issue ([#122718](https://github.com/kubernetes/kubernetes/pull/122718), [@pacoxu](https://github.com/pacoxu)) [SIG Node]
