	11	+Matrix is a chat system very similar to E-Mail. People have their account on one server but can write messages to anyone on other servers. For example @someprofessor:tum.de can communicate with @someresearcher:lmu.de.
21	21
22		-So people have their **account on one server** but can write messages **to anyone on other servers**.
23		-
	13	+You can create end-to-end encrypted personal or group chats that are not stored and dependent on a central authority like most other tools (ms teams, whatsapp, zoom, ...) . All your messages are synced between all your devices - web clients, desktop clients, smartphone apps. For additional security, encryption keys of contacts can be verified and then stored as trusted.

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.

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:
