I have added a version checker to the plugin, not sure why i didn't do this from that start, It will run when the server starts up and check spigot for the version and tell you if there is a new update and will give you a link to the spigot page.
Also added a command to show a players Auth code in chat, this was requested.
/securestaff code [username]
securestaff.code
This helps with new phones if the player didn't write down the code or lost it.
