Ok so my issue is that because the server is in offline mode this means that anyone can set a username of another player and join the game therefore exposing the coordinates of that player and therefore possibly their base etc.
So to fix this i want to make a hub that the player spawns into upon login and then when they have logged in with their password they can then teleport to the main world as they where, so that they can carry on from the same position as they where before.
Now, is there any plugin that is available to do this, and if not a plugin then by what method could i accomplish this task? has anyone done this before? Any insight into how it is i would go around doing this would be appreciated.
