==================
Groups inheritance
==================

Even though TYPO3 does not limit the depth of backend user group inheritance,
it's advisable to avoid complex setups. Typically, 1 or 2 levels of inheritance
should suffice. Such flat structures offer significant advantages over more complex,
deeper inheritances, including easier maintenance, updates, and verification
of the sources of specific permissions.

.. note::
    Avoid complex inheritance within backend user groups. One or two levels of inheritance should suffice and make permissions easier to maintain.
