Minecraft Whitelist, Ops, and Online-Mode

Whitelist

white-list=true
enforce-whitelist=true

Console:

whitelist add PlayerName
whitelist list
whitelist on

Ops

op PlayerName
deop PlayerName

Op levels (4 is full) live in ops.json. Prefer permission plugins for large communities instead of blanket op.

online-mode

online-mode=true

Keep true unless you knowingly run an offline network. Switching modes changes UUIDs and can orphan inventories.

Lockout recovery

If you lock yourself out, use the Pterodactyl console (it bypasses in-game auth) to whitelist add or op your account.

Frequently Asked Questions

online-mode=false risks?

Allows cracked/offline UUIDs and breaks many auth assumptions. Keep true for public Java SMPs.

How do I op myself?

From Pterodactyl console: op YourName — or edit ops.json carefully.

Whitelist blocks everyone?

Whitelist yourself first, then friends. Disable temporarily only while fixing.
