Identified

Microsoft has confirmed that the files previously flagged by Defender were false positives. Updated definitions are currently being propagated across their systems and are expected to be fully deployed within the next 12 hours.

Once we are confident that the Microsoft Defender security definitions have completely propagated, we will re-enable downloads of the latest Windows Platform Authenticator. The currently available version, 2.104.0, is available for download.

We appreciate your patience and will provide another update once we have confidence that the security definitions have propagated.
