You can sign into your Microsoft account without a password

Windows 10 October update has now been restored. This will allow consumers to enter their own Microsoft account without a password. Microsoft users can now log in to their accounts from Edge Browser, Windows Hello or FIDO2-based Security Device such as Yubico's YubiKey 5.

This method will require a fee scan or a PIN code.

This login method will only work for personal accounts only. Microsoft can release this feature for educational and business accounts at the beginning of next year.
