The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

/// tip

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, usw.

In diesem Beispiel verwenden wir **SQLite**, da es eine einzelne Datei verwendet und Python integrierte Unterstützung bietet. Sie können also dieses Beispiel kopieren und direkt ausführen.
