OpLock

by VoidLock

OpLock ties operator powers on a Fabric server to whether a given player is logged in, so OP is only active while the player is online.

FabricServer-side onlyMIT LicenseOpen source1.19.1 – 1.21.1

What it does

OpLock lets server administrators switch operator powers off and on with a command. When a player logs in, OP powers are enabled for that player, and when the player logs out they are disabled again. Server owners can also set the default so that players join with OP powers turned off until they log in. The mod needs Fabric API and runs on the server alone, so players join without installing anything. It is open source under the MIT License and published for 1.19.1 – 1.21.1.

Key features

  1. Toggle OP powers

    A command lets server admins turn operator powers on or off for players without changing their OP status.

  2. Login enables OP

    Operator powers switch on when the player logs in and switch off again when the player logs out.

  3. Logged-out default

    Server admins can make players join with OP powers disabled by default, then enable them after logging in.

Questions

Does OpLock need Fabric API?

Yes. Fabric API is a required dependency and must be installed on the server next to OpLock.

Do players need OpLock installed?

No. Players join without it, since only the server has to run the mod.
