IG Passwords for online-mode=false servers

My friend runs a bukkit server with online-mode=false so his friends can play, but sometimes we get people coming in on our accounts and F**king s**t up so is there a plugin kinda like mukkit, but not as complicated and web based?
Thanks

 

Why don't you just enable online-mode?

 

Because he wants his friends to play that cant afford the game yet, like xeology.

 

There is already a plugin.. (xAuth) or something

I run more than 1 server some are for ppl that pay only and some are for both.. xAuth comes in handy But server might lag a small bit when people join the server but its only for a short time
