🔒 Why AmethystGuard?
Operator access is one of the most powerful permissions on a Minecraft server. If an attacker manages to obtain OP, they can potentially take complete control of the server.
AmethystGuard adds an extra security layer around operator privileges and helps prevent unauthorized access before it becomes a serious problem.
💎 AmethystGuard because OP access should never be left unprotected.
