RVM - Vector WALL

# 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 1. **You** (admin or external system) add a player's UUID to the token database 2. **Player** connects to Velocity 3. **Plugin** checks if the UUID exists in the database 4. **If found** → player is allowed to join the server, token is deleted 5. **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
