    # Expire user sessions that have not been accessed within a certain period of time.
    # Expired users will be asked for credentials again.

    # == Columns
    #
    # This module expects and tracks this column on your user model:
    # - last_access_at - timestamp of the last access by the user
    #
    # == Configuration
    #
    # Timeoutable is enabled and configured with the `timeout_in` configuration parameter.
    # `timeout_in` expects a timestamp. Example:
    #
    #   Authenticate.configure do |config|
    #     config.timeout_in = 15.minutes
    #   end
    #
    # You must specify a non-nil timeout_in in your initializer to enable Timeoutable.
    #
    module Timeoutable
