Summary:

Details:
[Introduction]
We're introducing Microsoft Entra passkeys on Windows to enable phishing-resistant sign-in to Entra-protected resources. This update allows users to create device‑bound passkeys stored in the Windows Hello container and authenticate using Windows Hello methods (face, fingerprint, or PIN). It also expands passwordless authentication to Windows devices that aren't Entra‑joined or registered, helping organizations strengthen security and reduce reliance on passwords.
[When this will happen]
Public preview: Rolling out from mid-March 2026 through late April 2026
General Availability
Worldwide: Mid‑March 2026 to mid‑April 2026
GCC: Mid-April 2026 to mid-May 2026
GCC High: Mid-April 2026 to mid-May2026
DoD: Mid-April 2026 to Mid-May 2026

User Authentication Issues
If organizations do not prepare for the implementation of Microsoft Entra passkeys, users may face difficulties in authenticating to Entra-protected resources, especially if they are using unmanaged devices. This could lead to increased login failures and user frustration.
