How do I prevent people from registering / joining my server on heroku


After starting a rocket chat instance on, to my dismay I discovered that anyone with the URL can just join the team.

How can I make it private, i.e. that only people with invites can join?


The option was buried in the “Accounts” settings, under “Registration”: “Manually Approve New Users”. It took me about 90 minutes to find this.
