    * Si los datos son inválidos (por ejemplo, falta un campo), significa que el código de *tu* aplicación está defectuoso, no devolviendo lo que debería, y retornará un error del servidor en lugar de devolver datos incorrectos. De esta manera, tú y tus clientes pueden estar seguros de que recibirán los datos y la forma de los datos esperada.
* Agregar un **JSON Schema** para el response, en la *path operation* de OpenAPI.

#### The time to answer helps the attackers { #the-time-to-answer-helps-the-attackers }

At that point, by noticing that the server took some microseconds longer to send the "Incorrect username or password" response, the attackers will know that they got _something_ right, some of the initial letters were right.

#### Die Zeit zum Antworten hilft den Angreifern

Wenn die Angreifer zu diesem Zeitpunkt feststellen, dass der Server einige Mikrosekunden länger braucht, um die Antwort „Incorrect username or password“ zu senden, wissen sie, dass sie _etwas_ richtig gemacht haben, einige der Anfangsbuchstaben waren richtig.
