Quote:Microsoft is implementing a significant change to its account authentication system starting February 2025. Under the new system, users stay signed in across sessions unless they sign out explicitly.

To better understand the change, it is necessary to look at how sign ins are handled currently by Microsoft. When you sign in to a Microsoft account in a web browser, a "stay signed in" prompt is displayed after you provide username, password, and the optional two-factor authentication verification.
