Windows Single Sign-On 2024: Important Updates for EEA

In this blog, we discuss the upcoming changes to Windows Single Sign-On, an important development for users in the European Economic Area (EEA).

Reason for the Changes

Microsoft is adjusting its systems to comply with the Digital Markets Act (DMA) within the EEA. These changes affect how users log in to Windows apps.

What Can Users Expect?

Starting in early 2024, users in the EEA will see a notification when logging into Windows. This message asks if they want to use the same login credentials for other Microsoft apps. If users choose to use the same login credentials, this message no longer appears. If they choose otherwise, they can log in with different credentials or use the app unauthenticated.

Testing and Preparation

A sample version of Windows 11 has already been released to test these changes. These changes are being rolled out gradually to devices in the Windows Insider Program. The changes can be tested by logging in with a personal Microsoft account or a work or school Entra ID, then opening a supported app.

Frequently Asked Questions

• When does this message appear? Starting in January 2024, fully rolled out by March 2024.
• On which Windows versions does the message appear? Windows 10 and Windows 11.
• Who sees this message? Users logging in with a personal Microsoft account or work or school Entra ID, in an EEA region.
• How often does this message appear? Once per user per device. The notification appears again after 90 days or when deleting and adding a cloud account again.
• Can users refuse to use single sign-on technologies? Yes, users can choose not to log in or use a different account.

Conclusion

These changes to Windows Single Sign-On mark an important step for Microsoft in complying with the DMA. For users in the EEA, this means a changed login experience on Windows, giving them more control over their login credentials. It is important for IT professionals and end users to be aware of these changes and prepare accordingly.
