User Management Proxmox supports multiple users, roles, groups, and authentication realms. This is essential for any shared or production environment, as well as keeping access limited and secure. Authentication Realms available in Proxmox Linux PAM-   uses the host OS users (/etc/passwd). Root uses this realm Proxmox VE Authentication Server (PVE)-  built-in Proxmox user database. Best for creating non-root admin accounts and GUI access LDAP/Active Directory-   for enterprise integration   Creating and Setting up New User Create User Go to Datacenter > Permissions > Users Click Add Fill in:     • User name: e.g., homelab-admin     • Realm: Proxmox VE Authentication Server     • Password: set a strong password     • Email, First/Last Name: optional Click Add   Assigning Premissions Go to Datacenter > Permissions Click Add > User Permission Set:     • Path: / (root, grants access to everything)     • User: the user you just created     • Role: Administrator (for full access) or PVEVMAdmin (for VM management only) Click Add Built In Roles Administrator — full control PVEVMAdmin — manage VMs (no host configuration) PVEVMUser — view and use VMs, no configuration PVEDatastoreAdmin — manage storage PVEAuditor — read-only access Note : It is best practice to avoid using the root account for daily tasks. Create a named admin account for normal use.
