RVM VectorWall
Lightweight Velocity plugin with one-time token authentication
RVM VectorWall is a Velocity proxy plugin that provides secure server access through a one-time token (UUID) system. The plugin checks each connecting player's UUID against an HSQLDB database and only allows access to those whose UUID has been pre-added. After successful login, the token is automatically deleted, preventing reuse.
Main Mechanics
- You (admin or external system) add a player's UUID to the token database
- Player connects to Velocity
- Plugin checks if the UUID exists in the database
- If found → player is allowed to join the server, token is deleted
- If not found → player is rejected with an unauthorized access message
Features
- One-time tokens — each token is used only once
- Automatic deletion — token is removed immediately after successful login
- Logging — detailed logs for each successful or failed attempt
- Simple — no client-side mods required
- HSQLDB — embedded database, no separate server required
- Velocity 3.5.0+ — fully compatible with latest versions
Requirements
- Velocity 3.5.0 or higher
- Java 17 or higher
