GetUvRetriesCommand Class
Namespace: Yubico.YubiKey.Fido2.Commands Assembly: Yubico.YubiKey.dllGets the number of UV retries remaining for FIDO2.
public class GetUvRetriesCommand : Object, IYubiKeyCommand<GetUvRetriesResponse>Implements
Remarks
The number of UV attempts remaining may vary based the configured maximum and the number of failed attempts since the last successful verification. Use this command to query for the current number of retries remaining for this specific YubiKey.
The number of remaining UV attempts should also be displayed to the user, so that they know that they may be reaching the limit. Exhausting the number of UV retries is not as catastrophic as exhausting the number of PIN attempts. When the number of UV retries reaches 0, the authenticator will no longer attempt UV with the on-board sensor, and will instead require PIN entry. Once the PIN has been successfully entered, the UV retry count will be reset - even if it was previous blocked.
See the user manual entry on PIN protocols for a much more in depth guide to working with user verification within FIDO2.
