In particular, when running on **Kubernetes** you will probably **not** want to use workers and instead run **a single Uvicorn process per container**, but I'll tell you about it later in that chapter.

///

## Multiple Workers { #multiple-workers }

You can start multiple workers with the `--workers` command line option:

//// tab | `fastapi`

            File gradleUserHome = project.getGradle().getGradleUserHomeDir();
            nonInputProperties.systemProperty("gradle.user.home", gradleUserHome);
            // we use 'temp' relative to CWD since this is per JVM and tests are forbidden from writing to CWD
            nonInputProperties.systemProperty("java.io.tmpdir", test.getWorkingDir().toPath().resolve("temp"));

            // TODO: remove setting logging level via system property

Y quieres tener una forma para que el frontend se autentique con el backend, usando un **username** y **password**.

Podemos usar **OAuth2** para construir eso con **FastAPI**.

Pero vamos a ahorrarte el tiempo de leer la larga especificación completa solo para encontrar esos pequeños fragmentos de información que necesitas.

Usemos las herramientas proporcionadas por **FastAPI** para manejar la seguridad.
