Admin commands for juliak23

Paste into the server console (no leading slash needed there) or type in chat as an op. Whitelist, op and ban work while juliak23 is offline.

Reason

Add to whitelist

/whitelist add juliak23

Needs white-list=true in server.properties.

Remove from whitelist

/whitelist remove juliak23

Make operator

/op juliak23

Grants op-permission-level from server.properties (default 4).

Remove operator

/deop juliak23

Ban

/ban juliak23 Banned by an operator.

Bans by UUID, so it survives a rename.

Unban

/pardon juliak23

Kick

/kick juliak23 Kicked by an operator.

Only works while the player is online.

whitelist.json

[
  {
    "uuid": "c9401816-12c4-488e-a365-a32a3535391e",
    "name": "juliak23"
  }
]

Add the object to the array in your existing file, then run /whitelist reload.

ops.json

[
  {
    "uuid": "c9401816-12c4-488e-a365-a32a3535391e",
    "name": "juliak23",
    "level": 4,
    "bypassesPlayerLimit": false
  }
]

Level 4 is full admin (stop, op, ban). bypassesPlayerLimit lets an op join a full server.

banned-players.json

[
  {
    "uuid": "c9401816-12c4-488e-a365-a32a3535391e",
    "name": "juliak23",
    "created": "2026-09-16 08:06:40 +0000",
    "source": "Server",
    "expires": "forever",
    "reason": "Banned by an operator."
  }
]

Edit only while the server is stopped; a running server rewrites this file.

These files live in the server root next to server.properties. Need entries for a whole list of players? Use the whitelist and ban generator.

juliak23’s Minecraft UUID

juliak23’s permanent Minecraft UUID is c9401816-12c4-488e-a365-a32a3535391e (or c940181612c4488ea365a32a3535391e trimmed). Because usernames can change but the UUID never does, servers tie whitelist, ban, op and permission entries to this ID, so they keep working even if juliak23 renames. The block above also shows it as the NBT int array used by /data and data packs since 1.16, as the UUIDMost/UUIDLeast longs older worlds use, and the offline-mode UUID an online-mode=false server would generate for this name.

Whitelist, op or ban juliak23

Copy a command from the admin block and run it in the server console (without the slash) or in chat as an operator. Whitelist, op and ban work while juliak23 is offline; kick needs them online. If the server is stopped, paste the whitelist.json, ops.json or banned-players.json entry into the matching file next to server.properties instead.

Why is name history not shown?

Mojang removed the public name-history API in September 2022, so no tool can reliably show a player’s past usernames anymore. Only the current name resolves.
