Partial Online Mode

Partial Online Mode is a server-side Fabric mod for Minecraft 26.2 that keeps online-mode=true enabled while allowing administrators to grant specific player names offline access.

How it works

Use /allowplayer <name> to allow a player without a Microsoft-authenticated account to join. Everyone not on the allowlist continues through normal Mojang authentication.

Requirements

• Minecraft 26.2
• Fabric Loader
• Fabric API
• Java 25
• online-mode=true

Only the server needs this mod.

Commands

• /allowplayer <name>
• /allowplayer remove <name>
• /allowplayer list
• /partialonlinemode

Important security note

Anyone can impersonate an allowed name. Do not allow operator accounts or grant operator permissions to offline UUIDs.
