So when creating a discord now, you have an option for community or just for friends and such. What if you add an option for password-protected servers. The server owner would be able to set up a password to the discord. I know you could just hide all the channels from a certain role, but this way if someone is trying to keep a discord private like many are. There can be no possible way for raiders or other people to get into it without knowing the password.
The regular server invite can look normal, or maybe a lock next to it, but when you click "Accept Invite", it will pop up saying, "Oops, this server is password protection!" and then below it an option to type the password.
