+List Accounts
+=============
+
+This API returns all local user accounts.
+
+The api is::
+
+    GET /_synapse/admin/v2/users?from=0&limit=10&guests=false
+
+including an ``access_token`` of a server admin.
+The parameters ``from`` and ``limit`` are required only for pagination.
+By default, a ``limit`` of 100 is used.
+The parameter ``user_id`` can be used to select only users with user ids that
+contain this value.
+The parameter ``guests=false`` can be used to exclude guest users,
+default is to include guest users.
+The parameter ``deactivated=true`` can be used to include deactivated users,
+default is to exclude deactivated users.
+If the endpoint does not return a ``next_token`` then there are no more users left.
+It returns a JSON body like the following:
+
+.. code:: json
+
+    {
+        "users": [
+            {
+                "name": "<user_id1>",
+                "password_hash": "<password_hash1>",
+                "is_guest": 0,
+                "admin": 0,
+                "user_type": null,
+                "deactivated": 0
+            }, {
+                "name": "<user_id2>",
+                "password_hash": "<password_hash2>",
+                "is_guest": 0,
+                "admin": 1,
