+User Management
+~~~~~~~~~~~~~~~
+
+Proxmox Backup support several authentication realms, and you need to
+choose the realm when you add a new user. Possible realms are:
+
+:pam: Linux PAM standard authentication. Use this if you want to
+      authenticate as Linux system user (Users needs to exist on the
+      system).
+
+:pbs: Proxmox Backup Server realm. This type stores hashed passwords in
+      ``/etc/proxmox-backup/shadow.json``.
+
+After installation, there is a single user ``root@pam``, which
+corresponds to the Unix superuser. You can use the
+``proxmox-backup-manager`` command line tool to list or manipulate
+users:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user list
+  ┌─────────────┬────────┬────────┬───────────┬──────────┬─────────────────┬────────────────────┐
+  │ userid      │ enable │ expire │ firstname │ lastname │ email           │ comment            │
+  ╞═════════════╪════════╪════════╪═══════════╪══════════╪═════════════════╪════════════════════╡
+  │ root@pam    │      1 │        │           │          │                 │ Superuser          │
+  └─────────────┴────────┴────────┴───────────┴──────────┴─────────────────┴────────────────────┘
+
+The superuser has full administration rights on everything, so you
+normally want to add other users with less privileges:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user create john@pbs --email john@example.com
+
+The create command lets you specify many option like ``--email`` or
+``--password``, but you can update or change any of them using the
+update command later:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user update john@pbs --firstname John --lastname Smith
+  # proxmox-backup-manager user update john@pbs --comment "An example user."
+

+.. todo:: Mention how to set password without passing plaintext password as cli argument.
