# Chat, VoIP and social network with <img src="/images/XMPP_logo.png" width=100>
|
||
|
||
YunoHost comes installed with an instant messaging server Metronome which implements the [XMPP protocol](https://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol)(previously known as Jabber), by default.
|
||
|
||
This protocol is already used by millions of people around the world - it is an open protocol. All applications based on XMPP are compatible with each other: when using an XMPP client, you can interact with anybody who has an XMPP account.
|
||
|
||
XMPP is an extensible protocol - this means users can configure "extensions" to chatrooms, to share messages and files, and to make voice and video calls using XMPP.
|
||
|
||
## XMPP account
|
||
|
||
To use an XMPP account you need a username, which takes the format: `user@domain.tld`, and a password.
|
||
|
||
With YunoHost, an XMPP account is created for all YunoHost users automatically. The XMPP account credentials corresponds to the user's main email address and password.
|
||
|
||

Here is an exhaustive list of XMPP clients : https://en.wikipedia.org/wiki/Comparison_of_XMPP_clients
|
||
|
||
## Encrypt conversations with OMEMO
|
||
|
||
XMPP chats can be made secure and private using [OMEMO] encryption (https://xmpp.org/extensions/xep-0384.html), for instance using Gajim:
|
||
- Install `gajim` and the plugin `gajim-omemo`
|
||
- Enable the plugin in `Tools > Plugins`
|
||
- Enable it
|
||
- Enable the encryption in the chat with somebody who also has OMEMO
|
||
|
||
## Chatrooms
|
||
|
||
To create a chatroom (multi-user chat) on your YunoHost server, use the identifier `chatroomname@muc.yourdomain.tld`.
|
||
|
||
For this to work you need to [add the corresponding `muc.` DNS record](dns_config_fr) in the DNS configuration.
|
||
|
||
## VoIP and videoconferences
|
||
|
||
A practical tool to call an XMPP client, either with voice or voice+video, is to use the client [Jitsi](http://jitsi.org/).
