Object containing the necessary information for signing with a FIDO2 credential.

userVerificationstring

Level of user verification required for this FIDO2 authentication. Values: 'required' (user verification must occur), 'preferred' (user verification is preferred but not required), 'discouraged' (user verification should not occur). User verification typically involves biometrics, PIN, or other local authentication methods on the device.
