Certificate Change for eduroam

Published Dec 04, 2025

2025-12-02 there was a certificate change on eduroam.

System/Service: eduroam

Status: Some people are experiencing problems after changing certificates on eduroam. See eduroam at KTH

Who is affected: All of KTH

How the outage affects you: This normally means that clients will ask users to approve the new certificate and enter their username and network secret  again. To facilitate the configuration of clients and avoid problems with approving a new certificate, there is an installation tool with adaptation for the KTH environment - “ eduroam CAT  ” (Configuration Assistant Tool), on Eduroam CAT. The new (and old) CA root certificate is included in the tool. The tool is available for all common platforms.
