Why, if I use the authentication by user / password (Publisher) can I see the data sent in another BROKER without authentication?

Description
629/5000
Hello friends, I am implementing a project that uses user / password authentication. The publisher is thus:
self.client_mqtt = MQTTClient (self.CLIENT_ID, BROKER, PORT, NAME, MQTT_PASS)
On the other hand the BROKER is running mosquitto, this works well. But I've done tests with another BROKER on my PC and another client on my PC with: mosquitto_sub -d -t / #
The problem is that the PC client and the PC BROKER shows the data.
Why, if I use the authentication by user / password (Publisher) can I see the data sent in another BROKER without authentication?
I am doing something wrong?

Research direction
No source file or test is named. Start by reproducing the setup with MicroPython 1.9.3, MQTTClient, Mosquitto, and mosquitto_sub -d -t /, then inspect the connection and broker configuration to establish how the second broker receives the data. Done means the behavior is explained and any concrete code or configuration change is clearly scoped.
