This allows you to authenticate using a FIDO authenticator, such as a USB security key or a passkey in your computer's TPM protected by a Windows Hello PIN or biometrics, like a fingerprint.
 
-In Windows 10 and 11 prior to 22H2 Moment 4 (September 2023), if the TPM contains the private key needed to authenticate to the relying party (like a website), Windows will prioritize prompting for the user's challenge (like a PIN) for this TPM authenticator first. Windows will still provide an option to choose a different authenticator (like a USB security key) with an additional click. Otherwise, if the TPM does not contain the required secret, Windows will prompt you to insert a USB security key.
