Microsoft has introduced a new feature allowing Windows users to log into their Microsoft consumer accounts using a passkey, eliminating the need for traditional passwords. This passkey authentication method supports various password-less options such as Windows Hello, FIDO2 security keys, biometrics like facial scans or fingerprints, and device PINs.

These "consumer accounts" are personal accounts used for accessing a range of Microsoft services including Windows, Office, Outlook, OneDrive, and Xbox Live. The announcement coincides with World Password Day, with Microsoft aiming to enhance security against phishing attacks and eventually phase out passwords entirely.

Previously available for logging into websites and applications, passkey support is now extended to Microsoft accounts, streamlining the login process without requiring a password.

Passkeys, unlike passwords, utilize a cryptographic key pair where the private key remains securely stored on the user's device. This method enhances security as it eliminates the risk of password interception or theft, and it simplifies the login experience, reducing reliance on password memorization and minimizing risky practices such as password recycling.

Moreover, passkeys offer compatibility across various devices and operating systems, ensuring a seamless authentication process. However, Microsoft's approach of syncing passkeys across devices raises some security concerns, potentially compromising account security if accessed by unauthorized individuals.

To enable passkey support for Microsoft accounts, users can create a passkey through a provided link and select from options like facial recognition, fingerprint, PIN, or security key. Supported platforms include Windows 10 and newer, macOS Ventura and newer, Safari 16 or newer, ChromeOS, Chrome, Microsoft Edge 109, iOS 16 and newer, and Android 9 and newer. Upon signing in, users can select their passkey from the list and proceed with the authentication process using the chosen method.
