Idea Passwords for teams

I personally don't like this idea.
This is why:
In my opinion this is fine how it is. You can open a team and use a password if you wanted to. Just like what you suggested. If you don't want others joining, you should be able to close your team for a since of security. Not being able to claim land is already hard enough to manage with trying not to get raided. Some people use their team warps for warps to bases because they've used their max warp limit. I've done that before. I wouldn't enjoy it if someone raided us through my own team. Not even tracking you there, all they did was ./team go [name]. That simple. That's why I don't like it.
