Passkey guidance clarifies Windows prerequisites; no Entra feature launch is evidenced

The 16 May 2026 period was quiet: both changes were updates to Entra ID documentation, with no new features, previews, general-availability announcements, retirements, or Message Center notices. The meaningful update concerns passkey (FIDO2) device and Windows-version requirements; the other is a limited error-code table update.

  Passkey documentation clarifies device and Windows requirements

  The updated Entra ID Authentication Passkeys Fido2 guidance states that devices must support passkey (FIDO2) authentication. It identifies Windows 10 version 1903 or later as the best experience for Microsoft Entra joined devices and Windows 10 version 2004 or later for hybrid-joined devices. This is documentation guidance, not evidence of a new passkey capability or rollout milestone.

  Error-code documentation received a limited reference update

  The Entra ID Error Codes page was updated, but the supplied change only shows an Error/Description table structure and provides no specific new code, altered behavior, or administrator action. Treat this as a documentation maintenance change unless the detailed page reveals additional changes.
