Aternos cracked server issue — Auth mod doesn’t block chat/commands before login

So I’ve got an Aternos server running with cracked enabled (my friends don’t all have premium accounts). I added the Auth mod to handle passwords, but it’s kinda useless — before players /login or /register, they can still:

Type in chat

Run commands

Open F3 and see coords

Basically anyone can hop on with someone else’s name and start causing problems even if they haven’t logged in yet.

Is there a way to fix this on Aternos? Should I ditch Fabric + Auth mod and switch to Paper + AuthMe Reloaded instead? Or is there some config/other mod I’m missing to actually block everything until login?

Would appreciate any advice
