Using Linux containers has several advantages including **security**, **replicability**, **simplicity**, and others.

Nunca almacenes contraseñas de usuarios en texto plano. Siempre almacena un "hash seguro" que puedas verificar luego.

Si no lo sabes, aprenderás qué es un "hash de contraseña" en los [capítulos de seguridad](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.

## Múltiples modelos

Aquí tienes una idea general de cómo podrían ser los modelos con sus campos de contraseña y los lugares donde se utilizan:

     * @throws IOException if an I/O error occurs
     */
    SID getOwnerUser(boolean resolve) throws IOException;

    /**
     * Return an array of Access Control Entry (ACE) objects representing
     * the security descriptor associated with this file or directory.
     * <p>
     * Initially, the SIDs within each ACE will not be resolved however when

#       by Bash, Ksh, etc; in particular arrays are avoided.
#
#       The "traditional" practice of packing multiple parameters into a
#       space-separated string is a well documented source of bugs and security
#       problems, so this is (mostly) avoided, by progressively accumulating
#       options in "$@", and eventually passing that to Java.

#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,

모든 메시지는 동일한 WebSocket 연결을 사용합니다.

## `Depends` 및 기타 사용하기

WebSocket 엔드포인트에서 `fastapi`에서 다음을 가져와 사용할 수 있습니다:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

이들은 다른 FastAPI 엔드포인트/*경로 작동*과 동일하게 동작합니다:

{* ../../docs_src/websockets/tutorial002_an_py310.py hl[68:69,82] *}
