#### 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.

Agora, obtenha os dados do usuário do banco de dados (falso), usando o `username` do campo do formulário.

Se não existir tal usuário, retornaremos um erro dizendo "Incorrect username or password" (Nome de usuário ou senha incorretos).

Para o erro, usamos a exceção `HTTPException`:
