+Property scopes
+---------------
+
+User properties (Full name, Address, Website, Role, …) have specific visibility scopes (Private, Local, Federated, Published).
+
+The visibility scopes are explained below:
+
+:Private:
+  Contact details visible locally only
+:Local:
+  Contact details visible locally and through public link access on local instance
+:Federated:
+  Contact details visible locally, through public link access and on trusted federated servers.
+:Published:
+  Contact details visible locally, through public link access, on trusted federated servers and published to the public lookup server.
+
+The default values for each property for each new user is listed below, but you should consult the declaration of the ``DEFAULT_SCOPES`` constant in the ``OC\Accounts\AccountManager`` class (`see the code <https://github.com/nextcloud/server/blob/master/lib/private/Accounts/AccountManager.php>`_) to make sure these are up-to-date.

+If you'd like to override the value for one or several default visibility scopes, use the ``account_manager.default_property_scope`` ``config.php`` configuration key, which defaults to an empty array:
+
+.. code-block:: php
+
+  'account_manager.default_property_scope' => [
+    \OCP\Accounts\IAccountManager::PROPERTY_PHONE => \OCP\Accounts\IAccountManager::SCOPE_PRIVATE
+    \OCP\Accounts\IAccountManager::PROPERTY_ROLE => \OCP\Accounts\IAccountManager::SCOPE_FEDERATED
+  ]
+
+In the above example, the phone and role properties are respectively overritten to the private and federated scopes. Note that these changes will only apply to *new* users, not existing ones.
