+API Tokens
+----------
+
+Any authenticated user can generate API tokens which can in turn be used to
+configure various clients, instead of directly providing the username and
+password.
+
+API tokens serve two purposes:
+
+#. Easy revocation in case client gets compromised
+#. Limit permissions for each client/token within the users' permission
+
+An API token consists of two parts: an identifier consisting of the user name,
+the realm and a tokenname (``user@realm!tokenname``), and a secret value. Both
+need to be provided to the client in place of the user ID (``user@realm``) and
+the user password, respectively.
+
+The API token is passed from the client to the server by setting the
+``Authorization`` HTTP header with method ``PBSAPIToken`` to the value
+``TOKENID:TOKENSECRET``.
+
+Generating new tokens can done using ``proxmox-backup-manager`` or the GUI:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user generate-token john@pbs client1
+  Result: {
+    "tokenid": "john@pbs!client1",
+    "value": "d63e505a-e3ec-449a-9bc7-1da610d4ccde"
+  }
+
+.. note:: The displayed secret value needs to be saved, since it cannot be
+  displayed again after generating the API token.
+
+The ``user list-tokens`` sub-command can be used to display tokens and their
+metadata:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user list-tokens john@pbs
+  ┌──────────────────┬────────┬────────┬─────────┐
+  │ tokenid          │ enable │ expire │ comment │

+  │ john@pbs!client1 │      1 │        │         │
+  └──────────────────┴────────┴────────┴─────────┘

+Similarly, the ``user delete-token`` subcommand can be used to delete a token
+again.

+API Token permissions
+~~~~~~~~~~~~~~~~~~~~~
 
+API token permissions are calculated based on ACLs containing their ID
+independent of those of their corresponding user. The resulting permission set
+on a given path is then intersected with that of the corresponding user.
