I installed zigbee and mqtt as containers on Proxmox using the tteck helper script. This is working fine for about a week now.
However, when trying to access the container consoles I noticed that I am now faced with a login dialogue. I am pretty sure the console directly opened a shell before. I can access the zigbee web interface and am aware of the API key, but that does not seem to double as root password for either container.
Q: How can I login again? I did not notice a web interface option to set container credentials.
