About Anticheat & Security
Anticheat plugins compare what a client reports with what the game's rules allow, and act when they disagree. Good ones are predictive, meaning they simulate what the player should be able to do, and tolerant of lag so honest players are not punished by a bad connection.
Login plugins matter when your server is not authenticating players with Mojang, for example behind a proxy or in offline mode. Without one, anyone can join using another player's name. A login plugin adds registration and passwords; it replaces what online mode provides.
No anticheat is perfect and none replaces moderators. Tune any plugin on a test server with real players before it can issue bans, and keep a way for staff to review a flag before a punishment is final.
Frequently asked questions
Will an anticheat ban honest players? It can. Lag, unusual client mods and Bedrock players connected through a bridge can all look like cheating. Test with the exact setup your players use and start with warnings instead of automatic bans.
