• Matrix

  • The Matrix service enables secure, encrypted real-time communication in a simple way. Among other things, text messages can be sent and calls or video calls can be made.

What is matrix?

Matrix is an open protocol for real-time communication. It can be used with various programs (also called “clients”) to send text messages and make audio or video calls. End-to-end encryption is active by default, and it doesn’t matter which operator the other user is registered with. Users can communicate with other KIT users as well as with users at other institutions which operate a Matrix instance, e.g. TU Dresden. It is also possible to communicate with private persons using matrix.org.

Login and Clients

To make it as easy as possible to get started, KIT provides a client as an Internet page. You can reach it at element.matrix.kit.edu. Detailed documentation and help pages with illustrations are available at docs.matrix.kit.edu.

However, you can also use matrix with any other client, similar to how you can use e-mail with Outlook, Thunderbird, as a website, or on your smartphone. The client Element is available as a PC program, website and mobile app.

Alternatively, you can use the less complex client Fluffychat on the smartphone or Nheko on the PC. For a detailed list of available clients, visit matrix.org/clients-matrix.


Matrix accounts of KIT members always have the form @ab1234:kit.edu for employees and @uabcd:kit.edu for students. However, the login is always done with your KIT login username via the central authentication service of the SCC (Shibboleth).


With Matrix you can exchange text messages as well as make (video) calls. Chat rooms can be grouped into "spaces" to sort them for yourself or, if desired, to make this collection of chat rooms available to others.

Further functionality, so-called integrations, with which one can integrate BigBlueButton conferences or Etherpads, we cannot offer at present.
