Some Frequently Asked Questions are answered for you here.

Your Microsoft account is a combination of your email address (=username) and the password you use to log in to services such as OneDrive, Outlook or MS TEAMS. If you use any of these services in your company, you already have a Microsoft account.

How to log in my.VDMA with your corporate Microsoft account?

Why does VDMA/OE-A use a Microsoft service as a basis for its member area?

Since the GDPR, stricter conditions and obligations for the processing of personal data came into force. To ensure legally compliant processing of your personal data, VDMA/OE-A decided to use the Microsoft services to handle access to its member areas.  Hence, VDMA/OE-A chose a system that complies with the current security guidelines and legal requirements.

In addition, using Microsoft Teams gives the opportunity to implement new collaboration possibilities.

Who has access to my data?

Your registration is checked in your company network via a service from Microsoft. The VDMA/OE-A has no access to this and thus no access to your data.
