auth could not identify password

Hello. I am seeing this error/warning with rpi-mqtt-monitor v 0.10.1. Previous version did not have this error.

For another install on different machine, I see this warning.

From what I see in your first installation your service is not running with root user - if you want to use the options to restart your system, (not 100% sure but maybe the update via hass also needs root) you need to run the service as root.
You can check how you run your service - the file is located here /etc/systemd/system/rpi-mqtt-monitor.service
check the line saying User=, change the user to root and restart the service, the error/warning should stop.

Hi. Both the machines are not set to user=root yet the first installation shows different error message then the second installation.

I've changed the first installation to user=root and the error message is the same as the second installation now or is it just a log message??

second one is just a log message, its fine.
