There are some extra features to handle security apart from the ones covered in the [Tutorial - User Guide: Security](../../tutorial/security/index.md){.internal-link target=_blank}.

The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.
