# Simple OAuth2 with Password and Bearer

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password`

We are going to use **FastAPI** security utilities to get the `username` and `password`.

OAuth2 specifies that when using the "password flow" (that we are using) the client/user must send a `username` and `password` fields as form data.

Let's see that phrase by parts in the sections below:

* **Asynchronous Code**
* **`async` and `await`**
* **Coroutines**

## Asynchronous Code

Asynchronous code just means that the language 💬 has a way to tell the computer / program 🤖 that at some point in the code, it 🤖 will have to wait for *something else* to finish somewhere else. Let's say that *something else* is called "slow-file" 📝.

        KtPsiBasedSymbolPointer.createForSymbolFromPsi<KtPropertySymbol>(propertyPsi)
            ?.let(::KtFe10PsiDefaultBackingFieldSymbolPointer)
            ?: KtFe10NeverRestoringSymbolPointer()
    }

    override val returnType: KtType
        get() = withValidityAssertion { owningProperty.returnType }

        if (callableSymbol is KtValueParameterSymbol) {
            return callableSymbol.getAllOverriddenSymbols()
        }
        (callableSymbol.firSymbol as? FirIntersectionCallableSymbol)?.let { intersectionSymbol ->
            return intersectionSymbol.intersections.flatMap {
                getAllOverriddenSymbols(analysisSession.firSymbolBuilder.callableBuilder.buildCallableSymbol(it))
            }
        }

You can create your own custom response class, inheriting from `Response` and using it.

For example, let's say that you want to use <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, but with some custom settings not used in the included `ORJSONResponse` class.

Let's say you want it to return indented and formatted JSON, so you want to use the orjson option `orjson.OPT_INDENT_2`.
