Enum Constant	Description
DISCOURAGED	This value indicates that the Relying Party does not want user verification employed during the operation (e.g., in the interest of minimizing disruption to the user interaction flow).
PREFERRED	This value indicates that the Relying Party prefers user verification for the operation if possible, but will not fail the operation if the response does not have the AuthenticatorDataFlags.UV flag set.
REQUIRED	Indicates that the Relying Party requires user verification for the operation and will fail the operation if the response does not have the AuthenticatorDataFlags.UV flag set.
