When I am on my Minecraft PC server a player has come on under my name and has had op and my rank. After I ban them they are able to change there names and come back I keep banning them and they keep coming back. Not really sure what to do.


You could try running your server with online mode (which means you might have to purchase a copy of Minecraft) so that players have to authenticate (proof that they're themself) themselves before they can join.

Otherwise a plugin like this (one that prevents play until you separately authenticate yourself after logging in) that prevents others from reusing a taken name also works.

Otherwise, what you'll have to live with it, and ban yourself (to stop others from using your name) and deop yourself whenever you log out.

To set your server to online mode, go to your server.properties file and edit:




Either that or change your account's password and secure your email address.

  • I own a Minecraft Premium account. How do I set my server to online mode? – Snoopy Games Feb 16 at 4:44
  • @SnoopyGames See update. – aytimothy Feb 16 at 5:32
  • @Snoopy There is nothing called a "premium account"! If you've bought it under that name, immediately call your bank to refund the payment, because you've been scammed! Only buy accounts directly from minecraft.net! – Fabian Röling Feb 16 at 14:38

    @FabianRöling Minecraft Premium was the name of the paid Minecraft license back when they still offered a free version before 2015. see help.mojang.com/customer/en/portal/articles/… for more info. – Nzall Feb 16 at 15:32

    @Baumi Um... Whitelists won't work if the user can be literally anyone on that list. – aytimothy Feb 19 at 23:42
