Zoom

(you could take a quick look at this)

Zoom is a videoconference-software especially used for big lectures at Universität Hamburg.

Please read through the documentation provided by the Regional Computing Center at https://www.rrz.uni-hamburg.de/en/services/weitere/medienkompetenz/videokonferenzen/zoom.html and make yourself familiar with Zoom and the data-protection friendly usage of Zoom. Officially you can only join Zoom meetings with the Zoom client installed.
