On Monday, 28.9.2026 at 1 p.m., the certificate for authentication in the eduroam will be exchanged. All users of eduroam with tu-dresden.de Login are affected. The root certificate remains unchanged, so that no effects on the benefits are to be expected.
Other Notes:
The checksums of the eduroam certificate are under: https://faq.tickets.tu-dresden.de/v/ItemID=648
If the WLAN client requests a consent to the certificate and displays the data of the certificate, they can be compared to detect fraud attempts.
