Hi,
I already perform a little check and I can assure you that Joomla Access on the Joomla modules is provided by Joomla itself.
There is nothing to check in my module because there is nothing to do in a module for the access level.. It is by default and for all modules !
It is a core feature of Joomla... As you can see :
