But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware` { #use-corsmiddleware }

# OAuth2 with Password (and hashing), Bearer with JWT tokens { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

Now that we have all the security flow, let's make the application actually secure, using <abbr title="JSON Web Tokens">JWT</abbr> tokens and secure password hashing.

This code is something you can actually use in your application, save the password hashes in your database, etc.

前章から発展させて、完全なセキュリティフローに必要な不足部分を追加していきます。

## `username` と `password` を取得する { #get-the-username-and-password }

`username` と `password` を取得するために **FastAPI** のセキュリティユーティリティを使います。

OAuth2 では、「password flow」（ここで使用するフロー）を使う場合、クライアント/ユーザーはフォームデータとして `username` と `password` フィールドを送信する必要があります。

しかも、フィールド名はこの通りでなければなりません。つまり、`user-name` や `email` では動作しません。

setting [Transport.DisableKeepAlives] to `true` will disable connection reuse.
However, such performance degradation usually indicates improper configuration
or usage of [Transport] or [Client] in the first place, and a deeper look would
