Microsoft is advancing its commitment to passwordless security by testing updates to the WebAuthn API that will allow third-party passkey providers to authenticate on Windows 11. This development enhances the existing Windows Hello experience by integrating alternative biometric authentication options, such as facial recognition and fingerprints, which offer stronger security measures compared to traditional passwords. Since early October, Microsoft has collaborated with credential providers like 1Password and Bitwarden to implement a plugin authentication model for passkeys within Windows. Now, Windows Insider users in the Beta Channel can begin exploring these options with the rollout of Preview Build 22635.4515 (KB5046756).

Enhanced Authentication Options

Users will soon be able to choose third-party passkey providers, in addition to the native Windows option, for authentication via Windows Hello. This choice allows seamless security integration across different devices using passkeys established on mobile devices.

Technical Implementation

The updated WebAuthn API will forward authentication messages to chosen plugins, with the ability to process and return responses, empowering customized passkey creation and authentication. - **Open Development**: Microsoft has made source code available to assist developers in creating plugins compatible with their passkey solutions, supporting innovation across credential management platforms.

Broader Industry Collaboration

Microsoft's efforts are part of a larger movement, alongside the FIDO Alliance, to promote passkeys as a standard for secure, passwordless authentication, utilizing WebAuthn credentials. In addition to these authentication updates, Microsoft is rolling out features to enhance productivity and gaming experiences. Windows 11 users can now resume working on OneDrive files from iOS and Android devices directly on PCs running the latest Beta Preview. Furthermore, the introduction of Microsoft Edge Game Assist brings a new in-game browser optimized for PC gaming through the Game Bar. These initiatives are a clear demonstration of Microsoft’s ongoing focus on bolstering security and improving user experience across its platforms. Windows Insider participants are encouraged to provide feedback on these new features via the Feedback Hub under the Privacy > Passkey category.
