This change will provide you with an even more secure and seamless experience when accessing your WinCC OA resources.
What does this mean for you?
For existing accounts:
Your current accounts will continue to function as usual. You can log in via this link.
For new registrations:
From now on, new registrations are only possible via Siemens ID. You can easily register here: Siemens ID registration
No more waiting!
A major advantage of Siemens ID: Once you have registered, you can log in immediately and start downloading WinCC OA – no waiting for activation!
Already have a Siemens ID?
Perfect! If you already have a Siemens ID, you don't need to register again. Simply go to winccoa.com and log in as usual with your Siemens ID.
We are confident that this change will improve your experience and look forward to continuing to provide you with the best WinCC OA resources.
