But first, let's check some small concepts.

## In a hurry? { #in-a-hurry }

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.

## OAuth2 { #oauth2 }

OAuth2 is a specification that defines several ways to handle authentication and authorization.

        val credentialHeader = if (proxyAuthorization) "Proxy-Authorization" else "Authorization"
        val credential =
          Credentials.basic(
            auth.userName,
            String(auth.password),
            challenge.charset,
          )
        return request
          .newBuilder()
          .header(credentialHeader, credential)
          .build()
      }
    }

                int index = auth.indexOf(':');
                String user = index != -1 ? auth.substring(0, index) : auth;
                final String password = index != -1 ? auth.substring(index + 1) : "";
                index = user.indexOf('\\');
                if (index == -1) {
                    index = user.indexOf('/');
                }

            adduser --quiet \
                    --system \
                    --no-create-home \
                    --ingroup "$FESS_GROUP" \
                    --disabled-password \
                    --shell /bin/false \
                    --home "$FESS_USER_HOME"  \
                    "$FESS_USER"
            echo " OK"
        fi
    ;;
    abort-deconfigure|abort-upgrade|abort-remove)

    },

    PASSWORD {
      override fun urlString(value: String): String = "http://:$******@****.***/"

      override fun encodedValue(url: HttpUrl): String = url.encodedPassword

      override operator fun set(
        builder: HttpUrl.Builder,
        value: String,
      ) {
        builder.password(value)
      }

## Über Integrationen von Drittanbietern

In diesem Beispiel verwenden wir den OAuth2-Flow „Password“.

Das ist angemessen, wenn wir uns bei unserer eigenen Anwendung anmelden, wahrscheinlich mit unserem eigenen Frontend.

Weil wir darauf vertrauen können, dass es den `username` und das `password` erhält, welche wir kontrollieren.

    val encodedUsername: String = httpUrl.encodedUsername()
    val username: String = httpUrl.username()
    val encodedPassword: String = httpUrl.encodedPassword()
    val password: String = httpUrl.password()
    val host: String = httpUrl.host()
    val port: Int = httpUrl.port()
    val pathSize: Int = httpUrl.pathSize()
    val encodedPath: String = httpUrl.encodedPath()

  @Test
  fun sensitiveQueryParamsAreRedacted() {
    url = server.url("/api/login?user=test_user&authentication=basic&password=confidential_password")
    val networkInterceptor =
      HttpLoggingInterceptor(networkLogs).setLevel(
        Level.BASIC,
      )
    networkInterceptor.redactQueryParams("user", "passWord")

    val applicationInterceptor =
      HttpLoggingInterceptor(applicationLogs).setLevel(
        Level.BASIC,
