### Connect to a public broker
### Use a public broker
The Mosquitto project runs a [public broker](https://test.mosquitto.org). This is the easiest to set up, but there is no privacy as all messages are public. Use this only for testing purposes and not for real tracking of your devices or controlling your home. To use the public mosquitto broker, configure the MQTT integration to connect to broker `test.mosquitto.org` on port 1883 or 8883.
<div class='note'>
If you experience an error message like `Failed to connect due to exception: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed`, then add `certificate: auto` to your broker configuration and restart Home Assistant.

## Broker configuration
MQTT broker settings are configured when the MQTT integration is first setup, and can be changed if needed. To change the settings, click on "Configure" in the integration page in the UI, then "Re-configure MQTT".
MQTT broker settings are configured when the MQTT integration is first set up and can be changed later if needed.
Add the MQTT integration, then provide your broker's hostname (or IP address) and port and (if required) the username and password that Home Assistant should use. To change the settings later, click on "Configure" on the integration page in the UI, then "Re-configure MQTT".

If you experience an error message like `Failed to connect due to exception: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed`, then add
```yaml
mqtt:
certificate: auto
```
to your broker configuration and restart Home Assistant.
