On October 20th, 2025 the default login method has been changed to logging in via the Z-Wave Alliance (ZWA) Standards Developing Organization (SDO).
This means that you need to use your credentials of your ZWA SDO membership account (as used at sdomembers.z-wavealliance.org) to login to the ZCP.
Local ZCP credentials as used before October 20th have been deactivated.
This is the login to the Z-Wave Certification Portal (ZCP) via the Z-Wave Alliance (ZWA) Standards Developing Organization (SDO).
