-A comma separated list of login methods to use to authenticate the user.
-By default, Tryton supports only the `password` method which compare the
-password entered by the user against a stored hash. But other modules can
-define new methods (please refers to their documentation).
-The methods are tested following the order of the list.
+A comma separated list of the authentication methods to try when attempting to
+verify a user's identity. Each method is tried in turn, following the order of
+the list, until one succeeds. In order to allow `multi-factor authentication`_,
+individual methods can be combined together using a plus (`+`) symbol.
+
+Example::
+
+ authentications = password+sms,ldap
+
+By default, Tryton only supports the `password` method. This method compares
+the password entered by the user against a stored hash of the user's password.
+Other modules can define additional authentication methods, please refer to
+their documentation for more information.
Default: `password`
