hey this plugin is maybe a good plugin to prevent teaming

what is when i unlocked the door once THEN leave the team

will i be still able to open the door?

hey Herb, 

Once the door is unlocked the first time you're able to continue opening the door until the code lock is changed. If you've configured the plugin to allow teams and TC authed, and you're not TC authed or on the same Team you won't be able to change the code lock because it will prevent you from opening the code entering menu, however until it's changed by someone who can change it then you could continue opening the door since you know it's combination beforehand. 

I hope that helps.
