Proxmox VE default password & login
Bare-metal hypervisor based on Debian. The root user is created during installation; there is no factory default password — you set it on install.
Use these credentials for the very first login to Proxmox VE only. The full vendor documentation linked below explains how to rotate them and harden the install.
Notes & recovery
Login realm is "Linux PAM standard authentication". Web UI rejects login if PAM password is empty.

Anyone with internet access can try the published default on Proxmox VE. Set a strong, unique password the moment you finish first-time setup, ideally before exposing the service to your LAN.
