Establishing a Matrix Chat

What is matrix?

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.

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.

 Here you can find installation for IOS, Android, Mac, Linux and Windows.

Create new chat room

If you want to create a new chat room, first click the +-Button next to Rooms in the program or on the web inferface and then enter the name of the chat room. You can also block users on other servers from joining the room or enable encryption. You can't change these settings later. 

The chat room TestRoom is private, so it is not visible to others and participants can only join the room by invitation.

Invite into the chat

There are two types of chat, personal or group chat. You can create either personal or group chats.

For group chats, you can click the button Invite to this room to invite people to that chat. You can also privatly chat with other people in Matrix. If you want to chat with a member privatly, click on the +-Button beside People in the program or on the web interface.

Requirement: The member which is been invited has registered once on the Matrix Server. 

Note: If you have only released the room for the cit.tum or tum user, only people who are registered on the cit.tum or tum server can access this room.

Enter followings in the opened window:

For ITO Accounts: e.g. @musterma:cit.tum.de

For TUM Accounts: e.g. @lr89rbg:tum.de

For other Accounts:  e.g. @musterma:matrix.org

and send the invitation to the e-mail address of the person to be invited. The invitation will appear in the matrix chat window and must be accepted.
