Matrix Messenger
Matrix: The new Messenger for the University of Freiburg
Matrix Messenger enables efficient communication similar to WhatsApp, Telegram and Slack, for example, but with data protection-compliant encryption and its own hosting infrastructure provided by the University IT Service (Rz). With functions such as direct messages, group chats, fast file transfer and audio and video telephony, Matrix facilitates collaboration and the exchange of information in the student council, in courses, learning groups or research projects.
Matrix is the name of the open communication protocol. Element is used as a web, desktop or mobile application. The messenger enables federated communication both within the university and across institutions with Matrix users from other academic institutions, e.g. for project work.
Registration for Matrix is simply done via the UniAccount. This makes Matrix a comprehensive solution that meets the need for secure and efficient real-time communication between students and eliminates the need for workarounds in institutions and institutes.

Warning
Dear Matrix users,
Unfortunately, an error has recently occurred in the Element client. As a result, the security phrases/security key were not set correctly and you will probably lose access to your encrypted messages after logging out and back in.
How do you recognise whether you are affected by this problem?
A warning symbol in the form of a red shield with an exclamation mark will appear next to the messages you have sent:
Fortunately, we were able to identify all users affected by this problem and write to them individually by email. To set up your security phrase or security key correctly, we have provided a step-by-step guide [Link].
If you have any questions, simply write to the Matrix Messenger Support Team:
matrix-support@rz.uni-freiburg.de
Thank you for your help and good luck with setting up the encryption.
Best regards,
Your Matrix Messenger Support Team
