11 -Matrix is a chat system very similar to email. 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.

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.

22 - 1 [[matrix.tum.de (LRZ-TUM-ID)>>url:https://matrix.tum.de/#/welcome]]
23 -
24 -You can log in any of them with the appropriate ID and password.

110 +Since end-to-end encryption stores decryption keys only on clients (the "end"), logging out of the last client would mean loosing all messages.
178 178  
112 +Matrix allows to create a encrypted backup of the decryption keys on your homeserver - with a separate passphrase.

114 +Matrix will ask you to set up your secure backup, and will request the password for the backup keys if needed.
