For a longer transition period, we (WWU IT + WWUCA + DFN-PKI) offer worldwide recognized digital IDs (certificates) from two different providers.
The already longer offered digital IDs with “Global” certificates are based on the “T-TeleSec GlobalRoot Class 2” root certificate from T-Systems Enterprise Services GmbH.
This offer is expected to expire at the end of 2022 for server certificates and at the end of 2023 for other certificates.The now also offered digital IDs with “TCS” certificates from the Trusted Certificate Service (TCS) of the pan-European research network GÉANT are based on the root certificates of Sectigo.
The digital IDs „TCS“ have three advantages: For many users, no new ID checks are necessary, there is no paperwork, and digital IDs from servers can be automatically renewed via ACME.
