 ==== Session idle timeout
 
 You can use `xpack.security.session.idleTimeout` to expire sessions after a period of inactivity. This and `xpack.security.session.lifespan` are both highly recommended.
-By default, sessions expire after 1 hour of inactivity. To define another value for a sliding session expiration, set the  property in the `kibana.yml` configuration file. The idle timeout is formatted as a duration of `<count>[ms|s|m|h|d|w|M|Y]` (e.g. '20m', '24h', '7d', '1w'). For example, set the idle timeout to expire sessions after 30 minutes of inactivity:
