How to open whitelist on Minecraft Java server?

Whitelist limits the server's player access to accounts you allow. Add your own account first, then enable the list and try with two different accounts.

Step by step

  1. Run whitelist add OyuncuAdi in the server console. A forward slash is added to the command in the game's chat, usually not needed on console.

  2. Open the list with whitelist on. Check the accounts added with whitelist list and add another friend if necessary.

  3. Use whitelist remove OyuncuAdi to remove one. The enforce-whitelist setting can also affect when players who are already on the server are removed.

  4. Log in with a normal player on the list, then try again with a disallowed account. Using OP's account as the only test account.

Keep in mind

Access rules of other backend servers accessing the proxy network should also be checked.
