5		-There are two Matrix-Servers:
6		- 1 matrix.tum.de (LRZ-ID)
7		- 1 matrix.cit.tum.de (ITO-ID)
	4	+== What is Matrix? ==
8	8
9		-You can log in any of them with the appropriate ID and password.
10		-The Matrix Server is available as web but also as client. It can be found as web interface under the following links:

	10	+[[Matrix>>https://matrix.org/]] is a chat system very similar to E-Mail, but instantaneous and secure.
16	16
17		-[[ Here>>url:https://element.io/get-started]] you can find installation for IOS, Android, Mac, Linux and Windows.
	12	+* You need to register an account at a provider (e.g. tum.de, or lmu.de)
	13	+* Whatever your provider is, you can talk to people using other providers
	14	+** (((
	15	+For example {{code language="none"}}@someprofessor:tum.de{{/code}} can communicate with {{code language="none"}}@someresearcher:lmu.de{{/code}}!
	16	+)))
	17	+* (((
	18	+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!
	19	+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.
	20	+)))

	22	+So people have their **account on one server** but can write messages **to anyone on other servers**.

	25	+**Personal or group chats** are[[ end-to-end encrypted>>https://en.wikipedia.org/wiki/End-to-end_encryption]] and **not dependent on a central authority** like most other tools (MS Teams, WhatsApp, Zoom, ...) - anyone can host a Matrix server.
	26	+All your messages are **synced** between all your devices - web clients, desktop clients, smartphone apps.
	27	+For additional security, encryption keys of contacts can be verified and then stored as trusted.

	31	+Messages are stored and synced between home servers.
24	24
	33	+A user typically has **one account** on one homeserver.
	34	+You can use any homeserver of your choice - however **for TUM**, [[ITO>>doc:CIT.ITO.WebHome]] offers two homeservers:

26		-=== Log in to the web interface with TUM login data ===
	36	+* **matrix.cit.tum.de** for CIT accounts: @username:cit.tum.de
	37	+* **matrix.tum.de** for TUM accounts: @username:tum.de
27	27
	39	+You only need to use one account and can communicate with any other homeserver of the world.
28	28
	41	+If you don't have a CIT or TUM account, you can use a **public** homeserver instead:
