No need, you can create a password protected link that you can share so anybody can get in as a named guest. I host my own NC instance using the AIO docker since 2020 and since last year we’ve been using spreed (aka NC Talk). I manually added friends and family (each group with their own ACL rules) but also keep a live invite link for casual friends that might hop on a call every now and then. Password is just a safety measure so I don’t have randos joining the call/chat
