 ====Technical options ====

 For conferences with more than two parties, it offers encryption between each person's browser and your server, meaning that someone spying on your, or their, Internet connection cannot listen in to your call. It is not end-to-end encrypted, and so interception on your server would be possible — because of this, you need to be confident of the security of your installation.
+I find I get better performance by disabling p2p mode: it places more of a load of the server, but the resulting experience is better.
+===Nextcloud ===
+If you are using [[email_alternatives#Nextcloud|Nextcloud]] for file synchronisation or sharing (as an alternative to email), it also offers encrypted audio and video chat.
+I find the interface less pleasant to use that Jitsi, but you might find it works for you.

 If you think you have been scammed in this way, or are in the process of being scammed, get off the phone, disconnect your computer from the Internet quickly — pull out your Ethernet cable, or turn off the Wi-Fi adapter — and get your machine checked.
+====Safety and security for group calls ====
+===Add a password ===
+If the system you are using permits it, add a unique password to each call, and ask invitees to keep it private.
+===Create a unique ID for each meeting ===
+Some systems let you choose your own meeting ID. Do not use anything common, or containing identifying information. Instead, use a long meeting ID which is unlikely to be guessed or generated. Since most people are going to click on a link rather than try to type it in by hand, it is unlikely to matter how long or complicated it is.
+You could use a "UUID", which is a string like EF2B283C-3E5E-445C-8CC4-2BB363C00EA. You can either generate them on your computer (e.g. by running uuidgen if you use macOS) or else use a [[https://www.uuidgenerator.net|free online service]].
+Alternatively, you could use a sequence of random words (such as bodiment-semifloscule-hapteron-praesternal).
+===Reserve moderator / admin functions for yourself ===
+If you can, reserve moderator / admin functions — such as the ability to mute people, or kick people out of a call — to yourself.
+Not all services support this, so you might want to establish some ground rules at the beginning.
+===Keep an eye on the number of people in the meeting, and pause the meeting if an unexpected person joins ===
+You wouldn't carry on an offline meeting if someone unknown walked into the room, so don't do it online. If someone joins, and you don't know who they are, pause the meeting, and find out. If you are still not comfortable or satisfied, postpone the meeting.
