5	5

7		-[[Matrix>>https://matrix.org/]] is a chat system very similar to E-Mail, but instantaneous and secure.
	6	+There are two Matrix-Servers:
	7	+ 1 matrix.tum.de (LRZ-ID)
	8	+ 1 matrix.cit.tum.de (ITO-ID)
8	8
9		-* You need to register an account at a provider (e.g. tum.de, or lmu.de)
10		-* Whatever your provider is, you can talk to people using other providers
11		-** (((
12		-For example {{code language="none"}}@someprofessor:tum.de{{/code}} can communicate with {{code language="none"}}@someresearcher:lmu.de{{/code}}!
13		-)))
14		-* (((
15		-In the same way you can use Outlook or Thunderbird with the same email account, you can use different Matrix apps for the same Matrix account!
16		-Several apps exist, but we're going to go with "[[Element>>https://element.io/]]" for the sake of simplicity, as it's among the most fully-featured Matrix apps on the market.
17		-)))
	10	+You can log in any of them with the appropriate ID and password.
	11	+The Matrix Server is available as web but also as client. It can be found as web interface under the following links:
18	18
19		-So People have their **account on one server** but can write messages **to anyone on other servers**.
20		-
	13	+[[matrix.cit.tum.de (ITO- ID)>>url:https://matrix.cit.tum.de/#/welcome]]
21	21
22		-You can create[[ end-to-end encrypted>>https://en.wikipedia.org/wiki/End-to-end_encryption]] **personal or group chats** that are not stored and **not dependent on a central authority** like most other tools (MS Teams, WhatsApp, Zoom, ...).
23		-All your messages are **synced** between all your devices - web clients, desktop clients, smartphone apps.
24		-For additional security, encryption keys of contacts can be verified and then stored as trusted.

26		-== Home Server ==
27	27
28		-Messages are stored and synced between home servers.
	18	+[[ Here>>url:https://element.io/get-started]] you can find installation for IOS, Android, Mac, Linux and Windows.
29	29
30		-A user typically has **one account** on one homeserver. You can use any homeserver of your choice - however [[ITO>>doc:CIT.ITO.WebHome]] offers two homeservers:
	20	+[[image:elementdriver.png||width="1000"]]
31	31
32		-* **matrix.cit.tum.de** for CIT accounts: @username:cit.tum.de
33		-* **matrix.tum.de** for TUM accounts: @username:tum.de
34	34
35		-You only need to use one account and can communicate with any other homeserver of the world.
	23	+== Log in ==
36	36
37		-If you don't have a CIT or TUM account, you can use a public homeserver instead:
38	38
39		-* matrix.org: [[https:~~/~~/app.element.io/#/register>>https://app.element.io/#/register]]
40		-* or any other homeserver [[https:~~/~~/joinmatrix.org/servers/>>https://joinmatrix.org/servers/]]
41		-* or, host your own homeserver :)
42	42
43		-To use your home server, you have to **use a client** that communicates with your homeserver.
